Abstract
An induction motor is operated under sliding mode control such that the motor shaft position follows a predetermined trajectory. The motor drive's improved insensitivity to load disturbances makes it particularly well adapted to servo applications such as robot and machine tool applications. A sliding mode controller determines the correct torque command which causes the motor shaft position to follow the desired trajectory.
