摘要
双环控制的三相可控整流器具有优良的鲁棒性,但控制器参数选择会在很大程度上影响控制系统的动态性能和静态性能。本文提出了一种利用改进粒子群优化(PSO)算法实现控制器参数自整定,该算法结构简单、参数少、计算速度快、优化效果好。仿真结果表明,应用该算法整定的控制器参数,可使三相可控整流器的总谐波畸变率(THD)明显降低,并使其抗负载扰动能力有效增强。
The dual-loop control three-phase controllable rectifier has excellent robustness,still,the choice of controller parameters will affect the dynamic and static performance of the control system to a great extent.In this paper,an improved particle swarm optimization(PSO)algorithm is proposed to realize the controller parameter self-tuning.The algorithm has a simple structure and fewer parameters,its calculation speed and optimization effects are suit-able.The simulation results show that the practical values of load voltage and current of the three-phase controllable rectifier are increased.The total harmonic distortion(THD)of the three-phase controlled rectifier is small,and the ability to resist load disturbance is enhanced.
