为了实现感应电机高性能控制,克服运行过程参数摄动、不确定等问题的影响,应用反推原理设计的非线性控制器,考虑感应电机的铁损。并且通过李雅普诺夫理论证明控制器的整体稳定,采用电压空间矢量调制,应用于直接转矩控制系统。仿真结果表明,采用反推原理设计控制器能够使感应电机直接转矩控制达到很好的跟踪效果,具有推广意义。

In order to achieve high performance on induction motor control,to solve the parameter perturbations,uncertainties and other issues,the application of a nonlinear controller based on the principle of back-stepping was used,consider the induction motor iron loss in the static model to establish non-linear motor controller.The overall stability of the controller was proved by Lyapunov theory,using the voltage space vector modulation to direct torque control system.Simulation slows that using back-stepping controller enabled direct torque control of induction motors to achieve good tracking results.
