Improvement of the Starting and Braking Times of

Abstract

Within this present paper, an optimization method for the starting and braking times of the induction cage motor including magnetic saturation is proposed. This method allows us to start or to brake the motor with a raised electromagnetic torque and a limited current so as to enhance the starting or braking times. This method uses Lagrange optimization to solve a constrained problem that is: while keeping the current limited, get the maximum torque at each time. The principle of this method is presented and the possibility to regulate the speed is also proposed. At last, simulation results justify the fidelity of this method.
