This paper mainly focuses on the analysis of permanent magnet synchronous motor (PMSM) and its control system, based on the mathematical model of PMSM, a subsection control strategy is designed for PMSM in electric state, which is a combination of id = 0 control and weak magnetic control, in order to get a large speed range and get higher out- put power in the constant power region. The experiment platform of control system is built, the closed-loop control of the driving system for 2.5kw PMSM is realization, load control experiments that run below the base speed and no-load weak magnetic operation experiments that run above the base speed are carried out, phase current waveforms and weak magnet- ic control waveforms verify that the control strategy in this paper is correct and could achieve the desired control objec- tives.
