A new fuzzy controller based on an integrator algorithm for stator flux estimation in induction motors

Performance of the field orientation in induction motors depends on the accurate estimation of the flax vector. The voltage model used for field orientation has in the flux calculation process an open integration problem, which generally is solved with a feedback loop. In this paper, a fuzzy controller has been developed for the feedback loop of the integrator. The proposed controller has been tested on various motors of different power ratings, and it has been demonstrated that the neat algorithm is better than the system using a PI controller in, the feedback loop, The algorithm proposed to estimate. the stator flux of all induction motor has been simulated by using MATLAB-SIMULINK and implemented on an experimental system using a TMS320C31 digital signal processor.
