摘要
永磁同步电动机因其高可靠性和功率因数高等优点,广泛应用于各种交流伺服系统中。根据永磁直线同步电机数学模型,提出了永磁直线同步电机一个准线性化的并解耦模型,通过将初级电压作为控制系统输入,并进行反馈线性变换,然后通过固定边界层的滑模控制控制此非线性模型,保证了系统具有良好的鲁棒性,同时能够消除"抖振"。利用Matlab仿真软件建立此系统模型,并与传统PID控制方法进行了系统仿真与实验对比,验证了此方法具有较好的性能。
Permanent magnet synchronous motor （PMSM） has widely used in AC servo system for its advantages of high reliability and power factor. According to the mathematical model of permanent magnet linear synchronous motor, using the primary vohage as the input variable of the control system, after feedback linearization and its transformation, a quasi-linearization and decoupling model was derived. Then using sliding mode control to control this non-linear model to ensure the robustness of the system, at the same time it is able to eliminate the buffeting. Then established the model for this system by Matlab software and simulating compared with the traditional PID control method. System simulation and experiments verified the good performance of this method.
