At the same time, the simulation experimental analysis of the speed performance of the single- losed loop DC motor control system is made with changes of the parameter setting of speed regulator. The simulation waves of speed and current of DC motor are also given out. The experimental results show that the simulation results of speed performance of single closed loop DC motor are consistent with those obtained from theory, and this system offers guidance for experimental teaching.
