Abstract

This paper studies the application of H₂ optimal control to speed regulator for vector controlled induction motor drives. A mechanical movement model derived from vector control is employed in the design. An analytical optimal speed controller is obtained which has a form of PI controller. Simulation based on MATLAB/Simulink is carried out to verify the control scheme, and the results show that the designed controller has good speed tracking ability for various speed commands and is robust against load torque variations.
