Using MATLAB to simulate system under various parameters of a given. After according to automatic control theory, the design parameters of double closed loop speed regulation system were analysis and calculation, is obtained through the simulation of the parameter tuning of the basis. Speed and current double closed loop DC speed control system has good performance and is the most widely used of the DC motor, speed, current double closed loop DC speed control system of static and dynamic speed commodity specific quality regulation characteristics. The control law for the speed and current double closed loop DC speed control system, performance and characteristic of AC and DC power driven automation control system design method of varieties. First of all, it should be a basic part of the speed and current double closed loop DC speed control system and the static characteristic of; then, in the dynamic model of the system from the start immune based, establishment and its performance and speed of the two aspects and the two And the role of the regulators, and the third is the engineering design method of the basic regulation, the classical control theory, dynamic correction method, deduces the design method, that is, to calculate the advantages of simple, convenient, easy to master; the f
