| 摘 要： | 在表贴式永磁同步电机调速系统中，针对经典PI控制中超调大、鲁棒性差、易受负载扰动等问题，设计一种基于二阶滑模算法的控制器，采用积分型滑模面，通过李雅普诺夫函数证明了其在有限时间内收敛，将其应用于转速控制环节，具有对内部参数变化不敏感的优点；并针对负载扰动问题，设计一种负载转矩观测器，将负载转矩观测值补偿到电流中，减小了负载扰动对系统的影响。仿真和实验结果表明，该控制方法能改进永磁同步电机的调速性能，响应速度快且无超调，系统鲁棒性强。

| Abstract: | In the surface-mounted permanent magnet synchronous motor speed control system,the problems of large overshoot,poor robustness and susceptibility to load disturbance in classic PI control are addressed.A controller based on the second-order sliding mode algorithm was designed.The integral sliding mode surface was adopted.The convergence in finite time was proved by Lyapunov function,and it was applied to the speed control.It is insensitive to the change of internal parameters aiming at the problem of load disturbance,a load torque observer was designed to compensate the observed value of the load torque into the current to reduce the influence of the load disturbance on the system.Simulation and experimental results show that the control method improves the speed regulation system of the permanent magnet synchronous motor significantly,can respond quickly to a given speed without overshoot,and it has strong robustness. |
