Simulation of fuzzy PID double closed-loop DC speed regulation system base on Matlab

In this paper,aim at open-loop DC speed regulation system the large starting current,slowly speed adjusting and so on char-acters.double closed-loop control system is established,the simulation result indicates that:system performance index had the big enhance-ment.Base on this,the speed regulator uses the fuzzy control technology as outside controller,the inside use PI controller.the MAT-LAB simulation result shows that:DC speed regulation system 's performance index obtained certain optimization
