Adaptive Control of a Current-Fed Induction Motor

An adaptive nonlinear control system is presented for a currentsource inverter-fed induction motor. The approach to the control problem is fundamentally different to previous work in that it uses the steady-state model to formulate a nonlinear control which directly controls the shaft speed. The controller is adaptive, so neither load nor machine parameters need to be specified, although in practice the latter would always be known since they are required for the current-source inverter design.
