Research on High Precision and Stability of Three-Phase Rectifier based on Fractional Order PIλ Controller

摘要：

According to the demand of transmitter for deep exploration, this paper presents a strategy of current double closed loop control based on fractional order PIλ controller, which used to improve the tracing performance and anti-interference capability of the current regulating loop, also the stability of load current. And also presents a modified GA-PSO algorithm to get the parameters of fractional order PIλ controller. Results show that modified GA-PSO algorithm has faster convergence speed and higher accuracy, new control strategy using in three-phase PWM voltage rectifier has remarkably improved the stability and anti-interference capability of system.
