چکیده
|
Pid controller is used in most of the current-speed closed-loop control of permanent magnet synchronous motors (pmsm) servo system. however,kp,ki,and kd of pid are difficult to tune due to the multiple objectives. in order to obtain the optimal pid parameters,we adopt a nsga-ii to optimize the pid parameters in this paper. according to the practical requirement,several objective functions are defined. nsga-ii can search the optimal parameters according to the objective functions with better robustness. this approach provides a more theoretical basis for the optimization of pid parameters than the aggregation function method. the simulation results indicate that the system is valid,and the nsga-ii can obtain the pareto front of pid parameters. © 2014 qingyang xu et al.
