Paper Title:
Research on High Precision and Stability of Three-Phase Rectifier Based on Fractional PIλ Order Controller
  Abstract

According to the demand of transmitter for deep exploration, this paper presents a strategy of current double closed loop control based on fractional order 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 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.
