摘要
为了提高永磁同步电机(PMSM)伺服控制系统的响应速度和鲁棒性,文章提出了一种基于终端滑模的永磁同步电机控制方法.首先对传统滑模面收敛性进行分析,引入了非奇异终端滑模面;其次在传统趋近律的基础上提出了一种新型趋近律,并设计了基于新型的趋近律的电流-转速控制器;最后设计了滑模观测器对电机存在的扰动进行前馈补偿,并进行转速观测.通过软件仿真和实验证明,所提出的新型控制算法较好地抑制了永磁同步电机在接近平衡点时的抖振问题,且具有较低的超调量、良好的抗扰动能力和较快的响应速度,验证了所提方法的可行性和有效性.
Abstract
In order to improve the response speed and robustness of permanent magnet synchronous motor(PMSM)servo control system,a control method based on terminal sliding mode is proposed in this paper.Firstly,the convergence of traditional sliding mode surface is analyzed,and the non-singular terminal sliding mode surface is introduced.Secondly,a new approach law is proposed on the basis of the traditional approach law,and a current-speed controller based on the new approach law is designed.Finally,a sliding mode observer is designed to compensate the disturbance and observe the speed of the motor.The new control algorithm proposed has been demonstrated through software simulation and experimental verification to effectively suppress the oscillation issue of the permanent magnet synchronous motor when approaching the equilibrium point,and it has a lower overshoot,good disturbance rejection capability,and faster response speed,confirming the feasibility and effectiveness of the proposed method.
