Design and simulation of speed control of an induction motor taking core loss and stray load losses into account

In order to precisely control the torque and flux, core loss and stray load loss, which are generally neglected, should be considered in the mathematical model of induction motor (IM) to design the controller. Some of literatures have shown how the detuning can be done in the rotor field oriented (RFO) control system to compensate the effects of core loss and stray load loss. But it has seen that the mathematical modeling of detuning process is very complex which makes the complexity in the case of implementation also. In this paper, we design the RFO control system with consideration of both core-loss and stray load loss by including a decoupling control strategy which is easier than the detuning strategy. The effectiveness of the design control system has been verified by the simulation work which has been done by using Matlab/Simulink.
