Abstract-The use of the combination of photovoltaic energy source and the wind energy source as a hybrid configuration has become an alternative solution to produce power energy to fed industrial and domestic applications. In order to fully exploit the energy provided by both sources and ensure a very high efficiency it is necessary to oblige the hybrid power system to produce the maximum possible power. Indeed, in the applications based on renewable energy, power converters are used as an essential element that can help the global energy system to extract maximum power. This paper focuses on developing and optimising of a new architecture for hybrid photovoltaic generator (PVG) / wind turbine generator (WTG) power energy. To obtain the maximum power, two kinds of MPPT procedures have been used: the first is based on MPPT (P&O) sliding mode control (MPPTSMC) for the photovoltaic generator (PVG), and the second is a control based on MPPT current control (MPPTCC) approach and that for the wind turbine generator (WTG). In addition, the proposed hybrid power system can work very well under changes of climatic conditions, such as irradiation and wind speed. On the other hand, in order to maintain dc-link at a desired and stable value, during these variations, we have integrated a boost converter controlled by a sliding mode controller (SMC). A simulation model for the hybrid power system has been carried out using PSIM tools.

“…This nonlinear condition can be solved by using a controller that has a wide bandwidth of response such as the PI controller [84], the proportional-integral derivative (PID) controller which uses a genetic algorithm in order to determine the duty cycle gain for the controller [85], or by using the sliding mode controller (SMC) that has been proposed in [86,87,88].…”

Currently, renewable energy sources are the main driver for future electricity generation. This trend is growing faster in the developed countries in order to reduce the green house e ect and also in response to the limited supply of oil, gas and coal which are currently the major sources for electric generation. For example, the main renewable energy sources are from wind energy and solar energy but these energies are only available to those countries that are exposed to these resources. In this thesis an alternative energy source is investigated where it can be generated from the moving objects or in form of kinetic energy. The idea is to convert the kinetic energy during landing aircraft into electrical energy which it can also be stored and transferred to the existing electrical network. To convert this kinetic energy to electrical energy, the linear generator (LG) and uncontrolled recti er have been used for energy conversion. The LG have been modelled in 3-phase model or in dq model and combined with the diode recti er that is used to generate the dc signal outputs. Due to the uncontrolled recti er the electrical outputs will have decaying amplitude along the landing time. This condition also happen to the LG outputs such as the force and the power output. In order to control these outputs the cascaded buck-boost converter has been used. This converter is responsible to control the output current at the recti er and also the LG output power during landing to more controllable power output. Here, the H ∞ current control strategy has been used as it o ers a very good performance for current tracking and to increase the robustness of the controller. During landing huge power is produced at the beginning and when the landing time is increased, the generated input power from LG is reduced to zero. Due to this, the energy storage that consits of ultracapacitor, bidirectional converter and boost converter are usedin order to store and to release the energy depends on the input power source and load grid power. The voltage proportional-integral (PI) control strategy has been used for both the converters. The last part is to transfer the energy from the source and at the ultracapacitor to the load by using the inverter as the processing device. The power controller and current controller are used at the inverter in order to control the power ow between the inverter and the grid. This is when the reference power is determined from the load power in order to generate the reference current by using the voltage oriented controller (VOC), while the H ∞ current controller is used to regulate the inverter current in order to inject the suitable amount of current that refer to the load power. Finally, a complete energy recovery system for landing aircraft with the grid connection have been put together to make the whole system to be as a new renewable energy source for the future electricity generation.

“…the parameter variations of the load, which sometimes influence the tracking accuracy. Sliding mode control method [7] [8] [9] shows a good robustness against system parameter variations once the operating point enters the predefined sliding surface. However, it is difficult to design an optimal sliding surface that can adapt to all types of situations.…”

Quasi-PID control method that is able to effectively inhibit the inherent tracking error of PI control method is proposed on the basis of a rounded theoretical analysis of a model of switching power amplifiers (SPAs). To avoid the harmful impacts of the circuit parameter variations and the random disturbances on quasi-PID control method, a single neuron is introduced to endow it with self-adaptability. Quasi-PID control method and the single neuron combine with each other perfectly, and their formation is named as single-neuron adaptive quasi-PID control method. Simulation and experimental results show that single-neuron adaptive quasi-PID control method can accurately track both the predictable and the unpredictable waveforms. Quantitative analysis demonstrates that the accuracy of single-neuron adaptive quasi-PID control method is comparable to that of linear power amplifiers (LPAs) and so can fulfill the requirements of some high-accuracy applications, such as protective relay test. Such accuracy is very difficult to be achieved by many modern control methods for converter controls. Compared with other modern control methods, the programming realization of single-neuron adaptive quasi-PID control method is more suitable for real-time applications and realization on low-end microprocessors for its simple structure and lower computational complexity.
