永磁同步电机伺服控制系统建模与仿真

针对将自适应、模糊、神经网络等控制理论引入永磁同步电机(permanent magnet synchronous machine,PMSM)控制系统中设计太过复杂,难以达到较理想控制效果的问题,在Matlab/Simulink环境下,基于矢量控制策略对PMSM控制系统进行建模仿真。分析PMSM数学模型和空间电压矢量脉宽调制(space vector pulse width modulation,SVPWM)控制原理,建立基于SVPWM的PMSM控制系统仿真模型。仿真结果表明:该系统运行平稳,具有较好的静态和动态性能,符合理论分析,能为实际系统的设计与分析提供理论依据,对工程实践中系统的调试具有一定的指导意义。

Simulation and Modeling of Servo Control System of Permanent Magnet Synchronous Machine

Aiming at the complication of introducing the control theory such as adaptive, fuzzy, neural networks, etc to the permanent magnet synchronous machine （PMSM） control system, and the required control expectation can hardly be fulfilled, the vector control system of PMSM is simulated in Matlab/Simulink. Based on the analysis of PMSM model and the control theory of space vector pulse width modulation （SVPWM）, the simulation model of vector control system of PMSM is designed. The simulation result shows that the system runs stably, and gains good performance of static and dynamic response, complies with the theory analysis, provides the theoretical foundation of the design and analysis of real system, it can also be taken as reference for the system debugging.
