| Abstract: | This paper introduces a DC moter PWM servo-system controlled by a single chip computer.The system can be used in positioning digital controlled mechines and others. The system is characterized by the high accuracy and good reliability.The position loop of the system is adjusted by a single chip computer,which makes not only the struction of the system simply and the performance-price ratio increased,but also the controlling accuracy and reliability is better.Otherwise,the system has the function of the angle error display and adjusting the controlling parameters by keys.In the paper,the hardware diagram and software blowchart of the system and the experimental results are all presented.A measure of improving controlling accuracy is also presented at the end of the paper. |
