Abstract: For the problem that parameter uncertainty was usually neglected when inverse system theory was used in speed regulation system of induction motor, on the basis of non-linear model of induction motor, a pseudo-linear control system model of induction motor with uncertain rotor resistance and load was established by use of inverse system theory. A dithering-prevented and adaptive sliding mode variable-structure control method was proposed which was realized by use of variable exponential reaching law, and the control method was used in the pseudo-linear control system of induction motor. The simulation result showed that the control method can restrain uncertainty of system parameters and improve system stability and control accuracy.
