Computer simulation technology has been playing more and more important role in the research and analysis of AC drive system. The computer simulation can provide convenient, cheap, flexible and reliable model for us, through which the working characteristics of each part of AC drive system can be analyzed. And then, the optimal parameters are chosen and better system scheme is confirmed.To research the control performances of AC drive system deeply, it is necessary to research and analyze the computer simulation technology further. To fulfill the aim of improving and enhancing the control performances of AC drive system through simulating and analyzing each part of AC drive system. In this paper, the AC drive system is analyzed in three aspects: modeling, simulation technology and experiment research. Especially, the applications of PSpice and Matlab, the two most powerful simulation software, in AC drive system simulation are researched in this paper.Generally, in the first stage of design, the Simulink in Matlab is usually adopted to get the standard reference value using the ideal model. But in the next stage, PSpice is mostly used to perform the real characteristics simulation for the circuit. So the influence of system non-linear character, delay and response characteristics of the real components on the system is evaluated. Therefor, the powerful circuit simulation function of PSpice and the mighty calculation function of Matlab must be used synthetically. The component models, subsystems and subcircuits of PSpice are used to perform DC analysis, AC analysis, Transient analysis, Fourier analysis, temperature analysis, parametric analysis and Monte Carlo analysis etc. Then the system data analysis, output curve fitting, data integration, data division, statistical analysis and planar, three-dimensional plot are performed using Matlab.To begin with, the actualities, development trends of AC drive system and the model of PMSM are studied. The mathematics model and main control strategies of AC drive system are analyzed. And then the applications of PSpice and Matlab in AC drive system simulation are researched respectively and also their advantages and disadvantages in AC drive system simulation. The co-simulation technology of PSpice and Matlab is presented with emphasis in the fifth part. That is to get the simulation data of PSpice using Matlab. So PSpice and Matlabcan be used together in AC drive system simulation. In the last part of the paper, the experiment is carried out. The PMSM step motion control system is presented...
