摘要
该文详细介绍了永磁同步电机的数学模型和控制方法,在此基础上设计了一种基于自适应模糊算法的PMSM数字伺服系统。控制器通过模糊控制降低了模型不精确带来的影响,克服了系统的抖振问题且加强了系统的鲁棒性。经过仿真和实际实验表明,此控制方法可行,系统的抖振状况明显减弱,系统的动态品质得以提升。
In this paper,the mathematical model and control method of permanent magnet synchronous motor are introduced in detail.On this basis,a PMSM digital servo system based on adaptive fuzzy algorithm is designed.The fuzzy control of the controller reduces the influence of the imprecision of the model,overcomes the buffeting problem of the system and strengthens the robustness of the system.The simulation and practical experiments show that the control method is feasible and the buffeting condition of the system is obviously weakened,and the dynamic quality of the system can be improved.
