Rotor Position Simulation of Switched Reluctance Motor Based on Fuzzy Inference Rules

A non-linear mathematical model of switched reluctance motor is established, Based on the analysis of the relationship between psi-I-theta curve of motor, A new type of indirect rotor position estimation method using fuzzy inference rules is designed. The paper adopted MATLAB6.1 as a simulation tool, used for the simulation of fuzzy inference rules of rotor position angle, The simulation result shows that: Angle of rotor position measured changes continuously and smoothly in the required scope, The estimated results is very good.
