Research on single phase PWM rectifier based on nonlinear PID control theory
Based on the traditional linear control theory, single-phase voltage source PWM rectifier has the characteristics of the poor dynamic performance of system and parameters tuning difficulty in the control of single phase voltage source PWM rectifier. At first to the double closed loop of the single-phase voltage source PWM rectifier control as the basis, to analyze the PWM rectifier model of mathematical, and to introduce a new nonlinear function to optimize the control performance of voltage loop,a new type control scheme of single phase nonlinear PI controller is proposed. Finally, the simulation platform is built up by MATLAB software. Compared with the traditional PI controller,the simulation results show that calculation is simple and easy to implement,and the proposed method can not only significantly improve the dynamic performance of the system. also further enhance the anti-interference ability of the system.
