摘　　要：针对传统滑模控制系统中扰动信号的临界值难获得且计算量大的问题,提出了一种新型的自适应滑模增益的感应电机矢量控制技术,以便对感应电机进行快速准确调速.这种方法不需要大量的计算,消弱了对于各种扰动信号边界的依赖,实现了滑模增益随系统中的电机参数和负载转矩的扰动而进行自动调整的目的.并利用李亚普诺夫稳定定理,证明了该调速控制系统的稳定性.Matlab Simulink仿真结果表明:自适应滑模增益的变结构控制方法对于电机参数和负载转矩的不确定性均能呈现很好的调速性能,计算量小,鲁棒性好.Aiming at the problem of the limit value of various disturbance signals not only being difficult to obtain but also needing a large amount of calculation in the traditional sliding mode control system, a novel adaptive sliding mode gain vector control technology of induction motor is proposed, in order to control the speed of induction motor accurately and fast. This method does not require a large amount of calculation and weakens the dependence for the various disturbance signals boundary. The system realizes the automatic adjustment of the gain coefficient of sliding mode according to the motor parameters and load torque disturbance. By using Lyapunov stability theorem, the control system stability is proved. The simulation results of Matlab Simulink show that variable structure control method about adaptive sliding mode gain according motor parameters and load torque uncertainties has good speed performance, small amount of calculation and good robustness.
