摘要
采用有限元数据构建了直线开关磁阻电机的本体模型,并将快速非奇异终端滑模(FNTSM)控制算法应用到直线开关磁阻电机位置控制系统中。通过选择适当的切换函数和控制律,设计了位置控制器,提高电机控制系统的动态性能和鲁棒性。仿真验证了快速非奇异终端滑模相比于传统的PID控制具有响应速度快、无超调、鲁棒性强等优点,相对于传统的滑模控制(SMC)可明显削弱抖振,表明了快速非奇异终端滑模控制在直线开关磁阻电机位置控制系统中的优越性。
The finite element data was applied to build the ontology model of the linear switch reluctance motor, and the fast nonsingular terminal sliding mode control （FNTSM） algorithm was applied to linear switched reluctance motor posi- tion control system. By selecting the switching function and the proper control law, the position controller was designed to improve the dynamic performance and robustness of the motor control system. The simulations show that the fast nonsingular terminal sliding mode compared with the traditional PID control has quick response speed, no overshoot and strong robust- ness, compared with the traditional sliding mode control （SMC） can significantly weaken the chattering, which demon- strates the superiority of fast nonsingular terminal sliding mode control in linear switched reluctance motor position control system.
