A no chattering discrete-time sliding mode controller for field acceleration method induction motor drives

A discrete-time sliding-mode control is proposed for implementing an induction motor drive. Very simple constant gain reaching control and sliding control are obtained to eliminate the chattering phenomenon and steady state error as well as to achieve the robustness and minimized computation. For integration of the whole system, a simple field acceleration control algorithm is also derived to coordinate with the sliding mode control. It turns out that it is now possible to use a simple 8-b microcomputer to implement a high performance induction motor drive.<<ETX>>
