Abstract:In this paper, a nonlinear controller is presented for Doubly-Fed Induction Machine (DFIM) drives. The nonlinear controller is designed based on the input-output feedback linearization control technique, combined with a sliding-mode observer, using the fifth order mo del of the doubly-fed induction machine in fixed stator d-q axis reference frame with stator current and rotor flux components as state variables. The nonlinear controller can perfectly track the torque and flux reference signals in spite of stator and rotor resistance variations. In order to make the drive system capable of operating in the motoring and generating modes both below and above synchronous speed, two level SVM -PWM back-to-back voltage source inverters are employed in the rotor circuit. Computer simulation results obtained, confirm the effectiveness and validity of the proposed control approach.

“…For the DPC control, the switching signals that are used for the inverter switches are generated from the switching table, based on the error between the reference and the measured real and reactive power [13]. The advantage of using DPC is that the inner current loop and PWM switching model are not needed, because the switching is based on the look-up table that is based on the hysteresis control [98,106].…”

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.

“…In DPC, there are no internal current control loops and no pulse width-modulation (PWM), because the converter switching states are appropriately selected by a switching table. This last is based on the instantaneous errors, between the commanded and estimated values of the active and reactive power, and the power-source voltage vector position (classic DPC [20]) or virtual flux vector position (VF-DPC [22]). First of all, DPC is a widely used control strategy for three-phase PWM rectifiers [20,22].…”

rect power control of shunt active filter using high selectivity filter (HSF) under distorted or unbalanced conditions. Electric Power Systems Research, Elsevier, 2014, 108, pp.113-123. <10.1016/j.epsr.2013.006>. AbstractThis paper describes the design of a new configuration of direct power control (DPC) based on high selectivity filters (HSF) to achieve near-sinusoidal source current waveforms under different source voltage conditions. The proposed method uses the high selectivity filters instead of the classical extraction filters (low pass filters). The basic idea of the proposed DPC is to choose the best inverter voltage vector in order to minimize instantaneous active and reactive power errors using two hysteresis comparators. Their outputs associated with a switching table, control the active and reactive powers by selecting the optimal switching states of the inverter. Simulation results have proved excellent performance, and verify the validity of the proposed DPC scheme, which is much better than conventional DPC using low pass filters.
