The Research of Digital Double Close-Loop DC Speed Regulation System Based on ATMega8
The design of Digital Double Close-loop DC Speed Regulation System which we introduce in this article is based on the numeric control scheme, and using ATMega8 as the main controller, also with PI arithmetic, so as to construct a double close-loop DC Speed Regulation System with inner loop of current feedback and outer loop of speed feedback. The approach of motor speed regulation is through the voltage regulation. Experimental results show that the system has robustness, fast and good tracking performance.
