Characteristics Analysis of Load Simulation System Based on Permanent Magnet Synchronous Motor

Abstract:

This paper studies a load simulation system based on permanent magnet synchronous motor. Vector control principle of the loading motors vector control technology is analyzed, and using the strategy that direct-axis component of the stator current is zero, the mathematical model of load control is established. To analysis the control characteristics and lay a foundation for the control algorithm of the system, the control channel is divided into two channels, namely the forward load channel and disturbance channel, whose characteristics are analyzed, too. The torsional stiffness of the connecting link has an effect on the dynamics characteristics of the system. Therefore, the system dynamic characteristics under different torsional stiffness of forward load channel and disturbance channel are analyzed in the paper.
