摘　　要：采用非线性系统的微分几何方法对交流异步电机的数学方程进行变换，并在此基础上应用非线性变结构滑模设计理论指数趋近律方法进行设计，实现了一种较新的异步电机控制方法。由于采用了变结构控制，此系统对参数的变化不敏感，抗负载变化能力较强。计算机仿真及电机实验表明此方案可行，具有良好的动静态性能。A novel method of controlling induction motor is presented. The mathematical equations describing the dynamic behavior of an induction motor are firstly transformed according to the theory of monlinear differential geometry. Design method of the exponentially approaching rule of nonlinear variable structure theory (or sliding mode theory) is applied to the transformed state equtions and a novel control of induction motor is realized. Since variable structure contol is applied, the control system is insensitive to variations of the system parameters and is able to meet the situation of large variation of motor load. Results from both computer simulation and laboratory experiment of a tested motor show that this design leads to satisfactory static and dynamic performances of the motor.
