Research on control strategy of VIENNA rectifier based on sliding mode variable structure and IMC

Abstract

For the VIENNA rectifier,the DC side voltage is required to be stable and have good dynamic performance and robustness.A novel nonlinear control strategy for VIENNA rectifier based on IMC and sliding mode variable structure control is proposed.According to the main circuit topology, the mathematical model of VIENNA rectifier is established and a VIENNA rectifier controller based on internal model theory and sliding mode variable structure theory is designed.The simulation and experimental verification are carried out in this paper,the simulation and experimental results show that the control strategy can achieve the purpose of control effectively, and has the characteristics of robust, fast dynamic response, strong anti-interference ability and so on.
