During operation of the induction electric drive, its parameters included in the description of the mathematical model can change significantly. These processes involve heating of squirrel cage windings of the rotor, the saturation of the magnetic circuits of the rotor and the stator, and changes the given moment of inertia. The article considers the problem of tracking for a given angular velocity of the rotor under conditions of the uncertainty of parameters of the mathematical model, describing the behavior of the electric motor, and influence of uncontrolled external disturbances. The using of nonlinear discontinuous control law provides exponential convergence of tracking error to zero.
