Abstract

The state-space model of a synchronous phase convertor is formulated by using the nonlinear dynamic equations of both the pilot (synchronous) and the load (induction) motors. A design procedure is presented for computing the parameters of a linear controller for the field exciter of the synchronous motor. The controller parameters are updated according to the selected steady-state operating conditions. The proposed controller is suitable for microcomputer implementation. The validity of the controller design method is further verified by using computer simulation. Numerical experiments indicate that the synchronous phase convertor system can be operated stably under different load and fault conditions.
