Abstract:
Considering the structural characteristics of permanent magnet synchronous motor(PMSM),the paper analyzes the non-decoupling characteristics of traditional direct torque control(DTC)stator flux and torque double closed-loop control structure,and points out that the traditional double-loop control structure is not the best structure of torque control. Then,this paper presents a PMSM without flux linkage loop DTC method,which directly takes torque as the priority control target,no longer considers the control stator flux amplitude constant requirement,in order to achieve fast and accurate PMSM torque control. Simulation and the experimental results verify without flux linkage loop DTC method correct and feasible.
