| Abstract_FL | In order to solve the problem of PI parameters self-tuning about being dependent on accuracy of system mathematical model or long optimization time, a novel and practical parameters self-tuning and op-timization method for PMSM servo system was proposed. The method obtained optimal parameters of PI controller by combining parameters self-tuning ideas based on model and rules. Firstly, appropriate PI parameters by frequency-domain performance index was designed, such as cutoff frequency and phase margin of speed loop. Then with integrated time and absolute error (ITAE) as evaluation function, two-degrees-freedom iteration was utilized to seek PI parameters which made system obtain the minimum value of evaluation function in the vicinity of theoretical PI parameters. Thereby PI parameters were achieved which made PMSM servo system possess optimal control performance. The experimental results show that the optimized PI parameters makes PMSM servo system own good dynamic performance and load immunity. |
