| 摘 要： | 三相电压型PWM整流器的直接功率控制系统中,传统PI调节器很难抑制由负载变化或扰动引起直流电压的波动。而自抗扰控制对负载的变化和扰动可以准确地估计和补偿,从而有效抑制负载变化带来的影响,现采用ADRC进行电压外环控制构成控制系统。仿真结果表明:对于整流器的直接功率控制系统,基于ADRC的整流器的控制系统具有较强的鲁棒性和抗负载变化能力,其动态性能指标明显优于传统PID控制。

| Abstract: | Traditional PI controller cant restrain the DC voltage fluctuation caused by the disturbance or load changes in PWM rectifier control system.Active disturbance rejection controller can estimate accurately and compensate the load changes and disturbance,finally restrain the influence by the load changes,ADRC controller as a modulation a new control system was constituted.The simulation results show that the PWM rectifier control system based on ADRC has strong robustness and load change,dynamic performance i... |
