摘要
为实现对永磁同步电机高效率、高精度的控制,在传统SMC控制策略的基础上,提出一种基于NTSM的模糊滑模控制策略。通过采用非奇异滑模面代替传统SMC控制策略中的线性滑模面,有效地改进了线性滑模面中存在的不足。通过设计模糊控制器削弱SMC控制策略中的抖振现象。仿真和试验结果表明,提出的控制策略在电机启动、突增负载、突卸负载三种常见工况下具有较好的动态性能和稳态性能,有效地削弱了抖振,控制系统具有较好的抗干扰能力。
In order to realize high efficiency and high precision control of PMSM,a fuzzy sliding mode control strategy based on NTSM is proposed on the basis of traditional SMC control strategy.By using non-singular sliding surface instead of linear sliding surface in traditional SMC control strategy,the shortcomings of linear sliding surface are effectively improved.The chattering phenomenon in the SMC control strategy is weakened by designing a fuzzy controller.The simulation and test results show that the control strategy in this paper has good dynamic and steady-state performance under three common operating conditions of motor starting,sudden increase of load and sudden unloading of load,effectively weakening the chattering,and the control system has good anti-jamming ability.
