Application of Mutative Scale Chaos Search in Detecting the Rotor Orientation of Permanent Magnetic Spherical Motor
The permanent magnetic spherical stepper motor model is introduced in this paper, random encoder is painted on the rotor surface, and outputs of 96 optoelectronic sensors are used to identify rotor orientation. Based on the special structure and rotational character, the paper uses an improved mutative scale chaos search algorithm to mapping the dynamics equation of chaos variable to the orientation space. When the number of either local minima or cycles is equal to the initial value, the search space is dynamically reduced. Simulation shows that the search method is simple and has ability of fast convergence to the goal orientation, thus the search efficiency is improved.
