Hydraulic position servo control system is the integration of mechanical and electrical equipment in the most common automatic control devices, withHigh-power, high stiffness, high frequency response, etc., have a broad scope of application and wide application prospect. At present,Hydraulic servo system is widely used in areas such as military and aerospace. As electronic technology and control theory madeChin, hydraulic servo technology has also entered a new stage. In this paper, electronic systems and hydraulic systems, as well asIntelligent control of a combination of the latest achievements, the formation of intelligent digital hydraulic position servo control system. This is today's hydraulic servo control system, one of the important research direction, has an important practical value.Access to a large number of domestic and foreign in the literature on the basis of analysis of this issue both inside and outside the electro-hydraulic servo control system in intelligent control research in the field of the status quo, combined with the current PID control works in practice for more than 90% of the features of a DSP as the core control , and the PID control strategy with a wide range of intelligent control study of the combination of ideas and experimental research.TMS320F2812 Based on the design of the servo control system hardware, including power supply, clock, reset circuits, digital-to-analog conversion module, and the keyboard and display circuit design. Compared with the analog servo controller design greatly simplifies the hardware circuit and reduce the cost and shorten the reaction time and improved accuracy; In addition, this article analyzes the PID algorithm, as well as a variety of art based on the PID algorithm, the system has good dynamicQuality and steady-state performance
