Rotor Flux Oriented Implemented on DSP Control of Induction Machine

In this paper, a rotor flux oriented control system with flux and open-loop speed estimators is described. The key module of this system is the flux and speed estimator. In this paper, the speed estimation and rotor flux observation methods are studied using the theory of Model Reference Adaptive System and the control algorithm of 3-ph Induction Motor is deduced. The control algorithm is established successfully. Experiment carry out extended kalman filter algorithm to estimate the rotor fluxes and speed. One method of adaptive speed identification is designed successfully. The system uses the open-loop speed estimator to be the sensorless speed control. This prototype system is implemented on a digital signal processor (TMS320LF2407) in a 1.0 kW induction motor.
