摘要
为了优化永磁同步电机(PMSM)调速系统的动态性能,使用滑模控制的PMSM控制系统的非线性速度控制算法。提出一种新的快速积分终端滑模面(FITSMC),以提高传统积分终端滑模控制在速度误差远离平衡点时的跟踪误差收敛速度。针对高切换增益引起的大抖动现象,提出一种改进的抗干扰滑模速度控制器,该方法引入扩展状态观测器观测集中扰动,并在FITSMC中添加前馈补偿项。最后,通过仿真验证所提控制方法的有效性。结果表明:采用FITSMC替代传统的PI控制器,可以有效地降低动态速度跟踪误差。通过与传统方法进行比较,验证了所提方法(FITSMC+ESO)的优越性。
In order to optimize the dynamic performance of the permanent magnet synchronous motor(PMSM)speed control system,a nonlinear speed control algorithm of the PMSM control system with sliding mode control was used.A new fast integral terminal sliding mode control(FITSMC)was proposed to improve the tracking error convergence speed of the traditional integral terminal sliding mode control when the velocity error is far from the equilibrium point.Then,an improved anti-jamming sliding mode speed controller was proposed for the large jitter phenomenon caused by high switching gain.An extended state observer was introduced to observe lumped disturbances and a feedforward compensation term was added in FITSMC.Finally,the effectiveness of the proposed control method was verified by simulation.The results show that compared with the traditional PI controller,FITSMC can effectively reduce the dynamic speed tracking error.The superiority of the proposed method(FITSMC+ESO)is verified by comparison with the traditional method.
