This work presents an optimum approach to design phase-locked loop speed controllers（PLSC）.The primary design goal is to obtain good load disturbance response by minimizing the absolute control error of speed of brushless DC motor.In light of traditional phase-locked loop speed controller parameters optimization with manual cut and try method,a novel kind of phase-locked loop speed controller parameters optimization strategy based on ant colony algorithm（ACA）was proposed.ACA is a new category of bionic algorithm for optimization problems.Parallel computation mechanism is adopted in this algorithm.On the basis of brief introduction of ACA,a method for setting PLSC controller parameters using ACA was derived.A detailed realizing process of the new algorithm was also presented.In the end,this new phase-locked loop speed controller parameters optimization scheme was applied to high speed brushless DC motor of magnetically suspended gyroscope system.The simulation results show that the ACA based phase-locked loop speed controller parameters optimization has excellent adaptability and robustness.And the feasibility and effectiveness of this scheme is further verified.
