中文摘要: |
针对永磁同步电机调速系统存在的非线性、强耦合、多变量、参数摄动等问题。研究基于自抗扰技术的交流永磁同步电机直接转矩控制系统。为简化设计采用线性化的自抗扰控制算法,并对算法中的参数调整给出经验性的选取原则。仿真结果表明,该控制算法能够提高永磁同步电机调速系统的响应速度,减小稳态误差,无超调量,且抗干扰性和鲁棒性较强。 |
英文摘要: |
An Active Disturbance Rejection Control(ADRC) algorithm for the permanent magnet synchronous motor(PMSM) direct torque control system is designed, for the PMSM is a nonlinear, strong coupling, multi parameter perturbation variable system. The algorithm proposes a way of linear of the ADRC controller owing to the difficulty in parameters adjustment of ADRC. The simulation results show that this method can not only quicken the speed response of system without over shooting, but also reduce the error of the steady state. Further more, it is more robust to the load mutation and load disturbance. |
