Digital control of an induction motor drive by a stochastic estimator and airgap magnetic flux feedback loop

An approach for the problem of airgap flux estimation in induction motors is presented. The Kalman filter algorithm is developed to provide an estimated state vector containing flux linkage components. The estimated fluxes are then used to implement a direct flux control loop through an inverter-fed AC drive scheme. The overall control system is developed around a digital unit based on a 16 bit microprocessor and a signal processor.<
