An Improved Dynamic Control-based Hardware-in-the-Loop Laboratory Testing for Permanent Magnet Synchronous Motors

Abstract

This paper presents a new improved dynamic control (IDC) for the speed and currents of a surface-mounted permanent magnet synchronous motor (SMPMSM). In industry applications, standard proportional-integral (PI) controller is commonly used. Nonetheless, the load regulation capability and the tracking performance should be compromised in the designing process of the controller. The proposed IDC controller parameters are calculated based on the mechanical dynamic model and the predefined drive system performance. When the IDC parameters are obtained, the distinct speed performance can be accomplished at different operating conditions. A 850-W SMPMSM drive test setup, connected load, and the feedback sensors of the current and speed are emulated using the Typhoon Hardware-in-the-loop (HIL 402) tool with the dSPACE MicroLabBox. The performance of the proposed IDC scheme is evaluated through the verification results under rated speed reversal and load torque disturbance conditions. A comparative study between the proposed IDC and conventional PI controller is carried to confirm its simplicity, good performance, and robustness.
