摘要
根据模糊参数自整定PID控制和免疫调节机理,设计了一种模糊免疫PID控制器,该控制器综合了模糊控制,免疫调节规律与PID控制技术.将其应用于基于电压定向的直接功率控制中,改善传统PID控制器时整流器的工作性能.仿真结果表明,该方法具有高功率因数、低谐波、动态性能好等优点,并对负载扰动具有良好的抑制效果.
A fuzzy-immune-PID controller was designed based upon the principle of immune feedback control and fuzzy PID control with parameter self-tuning. The controller integrated fuzzy control, the rule of immune feedback control and PID control. The fuzzy-immune-PID controller was used in direct power control based on voltage orientation in 3-phase PWM rectifier to improve the performance of 3- phase PWM rectifier controlled by traditional PID controller. Test results showed that the fuzzy-immune-PID controller could achieve high power factor, low harmonic, good dynamic performance and possess better robust property to load-disturbance.
