| 摘 要： | 针对永磁同步电机结构复杂、模型非线性从而导致难以控制的问题,在分析永磁同步电机数学模型和SVPWM算法的基础上,利用Matlab/Simulink设计了一种基于SVPWM的永磁同步电机双闭环控制系统新模型,给出各子模块的具体设计模型。对＂积分斜率法＂产生三角波脉冲的方法进行了改进,最后对整个系统进行了仿真实验。仿真结果验证了该模型的正确性和有效性,为实际PMSM控制系统的设计提供了参考依据。

| Abstract: | Since the complex configuration of PMSM with model nonlinearity and control difficulty, the mathematical model of the PMSM and the algorithm of SVPWM are analyzed, a new model of PSMS double-loop control system based on SVPWM is designed with MATLAB/Simulink, and the concrete design model of each sub-module is given. A modified method of integral-slop for producing the triangle pulse is proposed. The simulation experiments for the whole system are carried out. The effective-ness and correctness of the model are verified by the simulation results. Therefore, a useful reference and basis are offered for the actual design of PSMS control system. |
