Improved fuzzy logic based research on energy saving control for induction motor

Based on a loss-included dynamic model of the induction motor, a simulation model was established using Simulink Matlab software. In a vector controlled system of induction motors, a mixed energy saving control method is put forward. Combined the fuzzy logic based control with the Rosenbrock method, this method can solve the oscillation and constringency problem around the optimal point stubbornly occurred in the typical fuzzy logic based algorithm. The simulation results show that the system achieves high efficiency operation by using the proposed method, when the load is changed. The energy saving target is obtained.
