Improved dynamic performance of the 3-phase induction motor using equivalent circuit parameter correction
The degradation of performance of the vector controller and hence the drive system response caused by transient variations of the rotor time constant such as those due to the skin effect in the rotor bars is discussed in this paper. These effects are investigated through the development of a detailed simulation of the motor and controller. Skin effect causes noticeable degradation of the system performance even when a relatively small error of 5% is introduced. As a result, a simple nonlinear compensation scheme has been proposed to reduce error to less than 1%.
