东北石油大学本科生毕业设计（论文） abstract
This paper first to servo system knowledge matting, learn to go with dynamic control system structure and definition, technical requirements and the developing situation, servo control system application fields are also mentioned in this article. Introduces the servo control system of the proportion of definition and classification, but also the main discusses the reality, the application of some of its typical applications are also discussed. And on this basis completed its hydraulic system of mathematical modeling and simulation of the system based on simulink tool box.
The first chapter of this paper mainly introduces the purpose, servo system development present situation and background, significance. The second chapter presents a dynamic system and proportion with servo system composition and definition. The third chapter presents the application of the system with dynamic ratio, and illustrates the simple principle and function, and the general enumerates some of the other areas of application. The last chapter of hydraulic proportional to follow-up system as an example, the mathematical modeling and simulation.
Key words：Servo system; Proportional control; Pneumatic; hydraulic
