Discrete Adaptive HCC Based FS-MPC with Constant Switching Frequency for PMSM Drives

Abstract

The finite set model predictive control (FS-MPC) exploits the advantages such as high dynamic response and flexibility. However, the spread spectrum due to variable switching frequency of FS-MPC is the main drawback associated with it. In this paper, a predictive control strategy with fixed switching frequency is proposed. A discrete adaptive based hysteresis current control (DAHCC) is combined with the basic FS-MPC as current controller to achieve constant switching frequency. The proposed current control strategy is implemented for voltage source inverter fed permanent magnet synchronous motor (PMSM). The system is implemented using the MATLAB/Simulink and system generator platform provided by Xilinx.
