Abstract: Aiming at the problems of complex parameter design and slow system dynamic response in the traditional double closed-loop PI control system of the Vienna rectifier, this paper proposes a novel double closed-loop control strategy of variable exponential approach law sliding mode control (SMC) and finite control set model predictive control (MPC). To begin with, a mathematical model of Vienna rectifier circuit is established. Then, the control algorithms of SMC voltage loop and MPC current loop are derived and designed. Finally, the applied control method is verified with simulation in MATLAB. The results show that the proposed system can improve the input current quality, and leads to a better steady-state response and dynamic performance of the DC output voltage, current and neutral point potential.

Keywords: Vienna rectifier; double closed-loop control; sliding mode control; model predictive control.
