Multi-objective genetic algorithms were applied to the parameter optimization of aeroengine proportional integral derivative(PID) controller.The PIDcontroller parameters of aeroengine were optimized by multi-objective genetic algorithms NSGA-Ⅱ.In this paper the controller parameters of an aeroengine was optimized
and the simulation results indicate that compared with the traditional optimization method
the speed controller system shows good dynamic and stable performance.The result is satisfactory.
