Hybrid systems are multi source systems that produce electricity independently of the main network(Island-mode). Hybrid systems have been receiving great interest due to tremendous application potential in remote areas, whereby power provision is challenging in terms of transmission and abundance. Hybrid systems make use of photovoltaic panels, fuel cells, and wind turbine to generate electricity from renewable energy resources. This book focuses on controlling active and reactive power in a hybrid systems. In the proposed hybrid, electricity is produced by two renewable energy devices, namely, PV panel and wind turbine. Storage battery plays an integral role in system back up and storing excess energy harvested from natural resources and using of diesel as supported. Matlab software are chosen for hybrid power system simulation.
The need for unrelenting increment in energy production, diminution in currently reliant fossil fuel resources, and the perception to plummet the CO2 emissions are the foremost factors for stipulating the growth of “Green Energy” generation systems based on renewable energy resources. Electrical energy requirements for many remote applications are too large to allow the cost-effective and constrained in reliable use of available stand-alone or autonomous renewable energy sources. In these cases, it may prove more feasible to combine several different types of power sources to form a system, is known as the "Hybrid" system. Hybrid Power Systems combine two or more energy conversion devices, or two or more fuels for the same device, that when integrated, overcome the limitations inherent in either. This book is a comprehensive study of various hybrid power system architectures and merits/demerits of each architecture. A new architecture using Motor-Synchronous generator set with Energy Management and Control unit instead of conventional inverters is proposed in this book to overcome these drawbacks.
Biological functions are the result of the interaction of many processes that connect different hierarchy levels going from macroscopic to microscopic level. Each process works in different way, and it is common to observe that changes in the conditions, such as nutrients or environment, modify the behavior of the systems. To approach these elements we consider the Hybrid Systems theory, which is adapted to reuse and reconcile models a priori validated. The aim in wine fermentation control is to predict fermentation problems in time to save them. Several models have been built trying to describe this process, but the models reach good predictions just when the process conditions are nearby to the tested ones. We defined a way to reconcile models within a hybrid model, deciding the equations depending on the system conditions. Understanding how cell fate decisions are taken, may allow controlling the cell commitment process. Being capable to modify the bone is a key element to treat disorders such as osteoporosis. We took a first step to test and analyze treatments of bone mass disorders in silico, currently we are improving our model to obtain more accurate predictions.
A number of academic and industrial researches incontrol systems have exposed the inherent weaknessesof PID control which are; rigidity, prohibitivecomputational complexity and non-applicability forintelligent and complex systems. Consequently, agroup of researchers have proposed fuzzy logiccontrol as a better alternative to PID control. Thisnotion has spawned numerous debates amongresearchers, experts and professionals in the fieldof control systems. As a result, this bookinvestigates and compares the performance oftraditional control techniques with fuzzy logiccontrol which will be optimized and made adaptive tothe variations of the sensor input. It will also beproven that fuzzy logic control is far more superiorin performance to the existing traditional controltechniques. These objectives were achieved throughthe use of MATLAB and SIMULINK to simulate, tweak andfine-tune the different cases for the response andtheir respective performance metrics. Interestinglyas expected, the results of the simulations showsthat fuzzy logic control, optimized or not, is betterthan the traditional control techniques, especially,PID control.
This book deals with fuzzy generalized PI-control method for hybrid active power filter, and new injection circuit topology. In this supply current detection control strategy is used. With this approach of injection circuit topology, in power system harmonics compensation down by using low capacity active power filter. The fuzzy generalized PI-control method is used. In this control method two control units present: a generalized integrator control unit and fuzzy adjuster system. This control method is useful to any other active power filters; also it is less expensive compare with new technologies like FACT systems and it very effective in compensation of harmonics. Compare to other HAPF control methods fuzzy generalized PI-control method have the advantages of faster response and low error of harmonic compensation in distribution system. The MATLAB simulation result shows that the new control method is very effective in reducing harmonics.
Described here is a novel microelectronic / microfluidic hybrid system that can control the motion of individual biological cells in fluids with microscopic resolution. The hybrid system starts with a microelectronic chip produced in a foundry using standard microfabrication techniques. A microfluidic channel is then fabricated on top of the microelectronic chip to provide biocompatible environments. Microelectronic devices actively interact with biological cells through electromagnetic fields to control the motion of individual cells in fluids. The unique combination of microelectronics and microfluidics, hence the new name microelectronic / microfluidic hybrid systems, provides unprecedented capabilities of cell manipulation, enabling researchers to carry out biological experiments in a standardized and repeatable manner.
In the last three decades the interest for monitoring systems applied to large-scale chemical processes has increased notably. This is essentially due to the need of guarantying safety operation conditions of the overall plant, related personnel and environment. Moreover, devices such as sensors and/or actuators can suffer malfunctions which worsening the framework to define the process global state. The increasing complexity in both plant designs and control policies require intelligent monitoring systems to support the decision making.The main objective of this book is addressing the fault detection, diagnosis and estimation system design integrated to fault-tolerant control for chemical processes. The procedure is focused on manage automatically the abnormal situation by the suitable interaction between the fault detection system and the plant-wide control structure. To achieve this purpose several engineering tools were improved and integrated, either for a single process unit or large-scale plants. In fact, hybrid-active designs based on historical data, classical and advanced control, signal processing, and multivariate statistics procedures were considered for this proposal
Nano-ordered composite materials consisting of organic polymers and inorganic compounds have been attracting attention for their use in creating high-performance or high-functionality polymeric materials. These materials are termed as “hybrid” which are blend of organic and inorganic components with molecular-level dispersions. Hybrid organic–inorganic materials are of two kinds: homogeneous systems derived from monomers or miscible organic and inorganic components, and heterogeneous and phase-separated systems with domains ranging from angstroms to micrometers in size. Integral to this definition is control over the size, composition, and topology of the organic and inorganic components, which depends upon the reaction and processing conditions used in the hybrid materials’ syntheses. The high degree of control over the composition and structure in hybrids permits systematic investigations of structure–property relationships which can result in improved mechanical, thermal, optical, or chemical properties relative to the organic or inorganic materials alone. Hybrid organic–inorganic materials are generally prepared through solution or sol-gel processing, in situ polymerization te

Currently, there are numerous location technologies that are used to determine the position of mobile devices in a space or grid, based on some mathematical models, where positioning means allowing a mobile device to be aware of its location with different degree of precision and accuracy. Unfortunately positioning systems have failed to grow in terms of usage by a common man as they haven''t been ubiquitous. The local positioning systems fail to work outdoors, whereas the conventional Global Navigation Satellite Systems (GNSS) based positioning systems do not work inside buildings due to the absence of line of sight to satellites. So there is a need for positioning systems that can work both indoors and outdoors, hence giving birth to the concept of Hybrid Positioning Systems (HyPos). In this book eight different HyPos are reviewed, which integrate technologies like RFID, CDMA, TV signal, Cell, Wi-Fi, and pseudolites for positioning. The systems are reviewed on the basis on availability, accuracy, and cost of development.
This book is very useful for the researchers who are working on wind, PV or Wind-PV hybrid power plants. Renewable energy from wind turbine and solar photovoltaic are the most environment-friendly type of energy to use. Because of combined benefits of renewable energy and hybrid system, a considerable interest has emerged in ‘renewable hybrid’ energy systems. This book, therefore, provides the case study of Wind, PV and Wind-PV hybrid system in different environmental conditions. The modeling of the system components and power control scheme is done using MATLAB/SIMULINK.
