Research on the Current Loop of PMLSM

Abstract:

Based on the basic vector control theory of motor, the paper deduces the decoupling control theory of PMLSM, and researches on the current loop of PMLSM servo system. Through introducing voltage compensation loop into the current loop, the paper analyzes the influences of the relevant parameters on the response speed of the system in details, and proves the theory that introducing voltage compensation into current loop is actually good for improving the response speed of the system from the perspective of theory and simulation, meanwhile, the paper also analyzes the influences of voltage compensation loop on the stability of the system.
