Abstract

The invention relates to a multi-objective optimization method for a double-closed-loop speed regulation system of a brushless DC motor. The multi-objective optimization for the double-closed-loop speed regulation system of a brushless DC motor is realized based on a quantum genetic algorithm, which can effectively solve the time-consuming and labor-intensive manual setting and large errors. And other problems, and overcome the difficulties of the previous algorithm "premature" and poor local convergence ability; in addition, the design of multi-objective fitness function can effectively prevent the damage of components caused by excessive control amount, which is conducive to obtaining a good speed control system.
