Abstract: | in this paper, a high-accuracy pulse current D. C. servo system is introduced,a variable stracture position Controller and a variable parameter robust adaptive speedregulator are proposed, in addition, the global stability analysis about the speed systemis established. In the system, the position. speed and current regulators are implementedby a 8097 chip-Computer, the main circait current is Time--discrete, Industry experiment shows that the Control effect is remarkable. |
