The Design and Simulation of Double Closed Loop DC Speed Control System Basing on Engineering Designing Method

In the engineering practice, double closed loop DC speed control is an applied method to control the speed, with plenty of advantages especially in the nature of resisting the disturbance than the single closed loop speed control. In addition, the engineering designing method is also a common way for the design of the system. In this paper, we adopt the engineering designing method to design the speed control system and made adequate simulation of our design by Simulink to make sure that our design is perfect. Finally we put forward a way for simulating the turnoff of the speed feed-back and deliver an academic analysis of the fault basing on the engineering designing method.
