【摘要】 针对永磁同步电机具有强耦合和强非线性特性的特点,在分析永磁同步电机数学模型和自抗扰控制原理的基础上,将自抗扰控制器应用于永磁同步电机的控制中,实现了永磁同步电机调速系统的自抗扰控制。仿真结果表明,这种自抗扰控制比P I控制有着更优的动态和稳态性能,并且使闭环系统在抗干扰性和鲁棒性上有了提高。更多还原

【Abstract】 Aimed at the characteristic of permanent magnet synchronous motor(PMSM) such as strong coupling and strong nonlinearity,the mathematical model of PMSM and the principle of active disturbance rejection control are analyzed first.Then active disturbance rejection controller is applied in the control of PMSM and is implemented in PMSM speed-adjusting system.Simulation results indicate that active disturbance rejection control not only has higher dynamic and static performance than PI control,but also improves the anti-disturbance and robustness abilities of the closed-loop system.更多还原
