摘　　要：目的为提高传统PID控制下永磁同步电动机在遇到负载突变、重载启动、频繁变速等外界条件变化时性能突变的问题,文中将超螺旋滑模引入电机控制中,以更好地应对外界条件的变化。方法通过在原有的超螺旋滑模算法中,加入自适应比例项和积分项,使其获得更快的收敛速度和更强的鲁棒性。然后引入一种新的过饱和系数,来应对引入积分项所带来的超调问题。结果在Matlab/SMULINK的仿真环境中,搭建所提方法的模型,并与传统的PID控制、超螺旋滑模控制以及比例项改进超螺旋滑模控制所搭建的模型做对比。结果表明,文中方法在遇到外界条件变化下,稳定性提高了33%~91%、快速性提高了27%~76%。结论文中优化后的超螺旋滑模控制器有更高的鲁棒性和更快的快速收敛性,改善了系统的性能,能够有效应对负载突变、重载启动、频繁变速等问题,使应用文中所提方法的永磁同步电动机能够更加符合包装机的要求。The work aims to apply super twisting sliding mode to motor control to better cope with environment changes to solve the performance change of permanent magnet synchronous machines(PMSM)under traditional PID control due to environment changes such as sudden load change,heavy load starting,and frequent speed changes.By adding adaptive proportional term and integral term to the original super spiral sliding mode algorithm,faster convergence speed and stronger robustness were obtained.Then,a new supersaturation coefficient was introduced to deal with the overshoot problem caused by the introduction of the integral term.In the simulation environment of Matlab/SMULINK,the proposed model was built and compared with the model built by the traditional PID control,super twisting sliding mode control and proportional term improved super twisting sliding mode control.The result showed that,the proposed method improved the stability and rapidity by 33%~91%and 27%~76%,respectively when the environment changed.The super spiral sliding mode controller optimized in this paper has higher robustness and faster rapid convergence,improves the performance of the system,and can effectively cope with the sudden load change,heavy load starting,and frequent speed change problems mentioned in the previous article.It makes the PMSM proposed in the work more conform to the requirements of packaging machine.
