A Fast Hysteresis Current–Controlled Permanent Magnet Synchronous Motor Drive Based on Field Orientation

摘要

A fast hysteresis current-controlled (HCC) permanent magnet synchronous motor (PMSM) drive based on field orientation is presented. The objectives of this research are to develop and utilize HCC algorithm for field orientation control (FOC) of a complete closed loop speed-controlled PMSM drive system, optimize the HCC algorithm to obtain fast speed response with step and ramp speed inputs to examine the effectiveness of current and torque tracking, identify the optimal control variables of the HCC on the PMSM, examine the performance with ramp and step reference speed inputs. The response of the developed model is compared with the speed response of the standard AC6 of MATLAB Simpower systems in terms of rise time, settling time and effectiveness of current and torque tracking. Compared to the standard AC6 of MATLAB Simpower systems, the developed model achieved rise time and settling time of 0.0108 seconds and 0.0143 seconds respectively while the corresponding values for AC6 model are 0.1944 seconds and 0.1984 seconds respectively. The developed model, therefore, offered superior performance over the AC6 model in terms of rise time, settling time and tracking capability.
