Internal Model Based Vector Control of Induction Motor
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 3
Abstract
This paper deals with the design of PID and Internal Model Controllers (IMC) in adjusting the speed of induction machine under disturbances and set point changes. The performance of PID controller is compared with IMC. The internal model control is an alternative to the classic feedback structure. Internal model control is composed of an inverse model connected in series with the plant and a forward model connected in parallel with the plant, this structure allows the error feedback to reflect the effect of disturbances and plant mismodelling resulting in a robust control loop. The IMC provides good performance and robustness against the disturbances in system when compared with the PID controller. A simulation study of these methods is presented using MATLAB/SIMULINK.
