Analysis Of Non-Linear Robust Control Strategies Of Switch Mode Dc To Ac Inverter With Reactive Load

摘要

Control strategies are having necessity to remain the output voltage stable for large disturbances at input as well as at output . A dc-to-ac inverter, w hich gives the nearer sinusoidal output by using nonlinear robust control based on the dc-to-dc converter topology. Computer simulation results show the robustness and fast dyna mical response of the control system. Then the nonlinear control law has been extended to a bidirectional inverter to overcome some of the drawbacks. The stability analysis of the control system is presented. The closed loop control system under P control, Pl control, PD control and PID control of the voltage loop for different types of loads are investig ated. The results show that the PD control is the best choice. All the work is carried out in MATLAB simulation environment and the results are presented
