GA searches a population of points in parallel instead of a single point. 2. GA does not require derivative information or other auxiliary knowledge; only the objective function and the corresponding fitness levels will influence the directions of search. 3. GA uses probabilistic transition rules instead of deterministic ones. In this book, a real-coded genetic algorithm is proposed to optimize the extended Kalman filter (EKF) for estimating the rotor speed of an induction motor. It is shown that the real-coded GA is effective for optimizing the EKF performance of three different controllers, namely the closedloop V/Hz controller, DSC, and FOC.
Based on the nonlinear control theory as well as the human ability to comprehend, reason, and learn, intelligent techniques may be used to overcome the above difficulties. 7 17 Intelligent Induction Motor Control Schemes Intelligence is defined as the ability to comprehend, reason, and learn. The definition of intelligent control from Astr€ om and McAvoy has been used widely: ‘An intelligent control system has the ability to comprehend, reason, and learn about processes, disturbances and operating conditions in order to optimize the performance of the process under consideration’ (Astr€ om and Bj€ orn, 1995).
