带恒功率负载的三相电压型PWM整流器无源控制研究
Research on passivity-based control of three-phase voltage PWM rectifier with constant power load
摘要
Abstract
Aiming at the problem that three-phase voltage PWM rectifier with constant power load may cause instability,a passivity-based control strategy of three-phase voltage PWM rectifier is adopted to solve this problem.By establishing the EL model of three-phase voltage PWM rectifier with constant power load,the passivity-based controller is designed.In this paper,a power observer is introduced to observe the unknown power in the actual project in real time,and the simulation model is built by MATLAB/Simulink.The simulation results show that the control strategy proposed in this paper has stronger dynamic and steady-state performance compared with the PI double closed-loop control and the PI inner loop passivity-based control strategy,which proves the feasibility of the proposed control strategy.关键词
