摘要
为了提高三相电压型PWM整流器的控制性能,同时考虑到PWM整流器非线性、强耦合的特点,给出了一种三相PWM整流器H2/H∞混合控制策略。针对H2/H∞混合控制器采用传统方法求解增加系统保守性的问题,采用粒子群优化算法进行H2/H∞混合控制器的求解。通过仿真证明了三相PWM整流器采用H2/H∞混合控制比传统的PI控制拥有更加良好的控制性能。
Considering the strong coupling and nonlinear characteristics of three-phase PWM rectifier, a mixed H2/H∞ control strategy is proposed in order to enhance the performance of the rectifier. And in view of the increased system conservation by traditional method, the particle swarm optimization （PSO） algorithm is applied for the controller solution. Finally, the simulation results indicate that the mixed H2/H∞ controller has better performance than the traditional PI controller in three-phase PWM rectifier.
