Usually a digital control system has higher response precision than a simulative one: in the meantime with the development of the digital angle sensor, a computer control system becomes easy to be used. But the real-time application is limited by the operation speed of the computer, especially for a multi-loops system controlled by one CPU. In this paper, a digitized servo system design for tracing table based on DSP TMS 320×240 is presented. It fully utilizes the wealthy peripherals and high-speed calculation function of DSP, makes the system structure simple, and uses the method of human simulating intelligent control. Experimental results show that the system has a compact structure and good dynamic and static characteristics.
