Abstract

This paper studies design of the speed sensorless field oriented control of induction motors considering sudden change of the rotor speed. The controller gains are designed to follow the dynamics of the sudden change of the rotor speed based on an induction motor and current control system model. The primary angular frequency can be estimated properly even when the rotor speed changed suddenly by designing the controller. Also, the time to converge to the command values of the stator current and motor torque is shortened. The effectiveness of the designing method is evaluated by means of simulating slip of the railway vehicle traction.
