This paper put forward a new method of designing Double Loop DC Motor Control System(DLM).Firstly,under the environment of Matlab and Simulink, we correctly set up the simulation diagram of the DLM.Then, we establish the optimization model with typical performance criteria as object function and the parameter numerical ranges as the constraints.Finally, a innovative genetic algorithm is presented to solve the optimization ranges as the constraints. Finally, a innovative genetic algorithm is presented to solve the optimization problem. The yielded solutions greatly improve the performance of the system.
