Abstract

The invention discloses a brushless DC motor position tracking controller based on fuzzy control, comprising a fuzzy position regulator, a speed regulator, a gain regulator, a DC brushless motor and position sensors, wherein three position sensors are installed in the motor, with a difference of 120 DEG between every two adjacent sensors; the fuzzy position regulator, the speed regulator, the gain regulator, the DC brushless motor and the position sensors are in connection in an electric loop mode to form a brushless DC motor controller based on fuzzy control. The brushless DC motor position tracking controller has the characteristics of simple circuit, low cost, interference resistance and good dynamic / static state servo characteristic, and effectively solves the problem of low tracking precision of a traditional control algorithm by realizing a fuzzy control algorithm in a DSP.
