Abstract :
A novel design of optimal sliding mode control of AC drive systems for improving the robustness of the system against external disturbances is developed. A quantitative analysis of robustness of the control system for a cage-induction machine drive is presented. The time-domain expressions of the transient speed deviation and maximum speed drop of the drive system, with sliding mode control. due to sudden-load variations are obtained. Analytic solutions for optimal switching vector and feedback matrix are directly related to the system dynamic specifications and drive parameters. Digital simulation and experimental results verify the theoretical analysis and control design
