设计一种由非线性控制方法实现的直接转矩控制矩阵变换器(DTC-MC)交流调速系统.首先构造基于扩张状态观测器(ESO)的自抗扰控制器(ADRC),取代传统DTC中的PI调节器,用来估计系统的扰动项并进行前馈补偿;然后运用多Lyapunov函数法对二阶ESO的稳定性进行分析.仿真结果表明,该方法提高了系统在输入电压非正常工况下的抗干扰能力和鲁棒性.

@@@@A fusion technology for the matrix converter(MC) and direct torque control(DTC) is proposed by using nonlinear control method. An active disturbance rejection controller(ADRC) based on the extension state observer(ESO) is applied to the system, taking the place of the traditional proportional-integral controller.The system stability of the second order extension state observer is studied by using multiple Lyapunov function method. By using this controller,the anti-disturbance capability and robust characteristics of the drive system under abnormal input voltage conditions can be enhanced. Simulation results show the effectiveness of the designed controller.
