Off-line Parameter Estimation of Three Phase Induction Motor using Advanced Computation Techniques

Abstract

The induction motor ratings are readily available or in most cases given by manufacturer of the motor but in order to implement vector control scheme on induction motor estimation of parameters with minimum error is highly desirable. There are several approaches proposed in literature for estimating parameters of motor in the online mode but these controllers as well as their control methods have always been very niche and propriety based leading to their limited usage. This project aims at proposing an offline method for estimating the parameters of the induction motor and optimizing the estimated parameters using various random search techniques for better drive control and performance. The proposed offline methods would also serve as an alternative method for the conventional parameter estimation tests like no-load test and blocked rotor test leading the better up-time and implementation time of the complete drive system.
