爬行

In the system of high precision and low speed, Because of the existence of the nonlinear friction, the static and dynamic performance of the servo system is very bad, such as stick slip, hunting, large error and so on, Because the traditional control of PID is hard to solve the nonlinear problem of the servo system, so this paper begins to introduce a new control method which is named adaptive fuzzy PID, It utilizes the rule of the fuzzy control to adjust the parameter of proportion, integral and differential on line, So this control method has some intelligence to improve the static and dynamic performance of the servo system.

在高精度、超低速伺服系统中，由于非线性摩擦环节的存在，使系统的动态及静态性能受到很大程度的影响，主要表现为低速时出现爬行现象，稳态时有较大的静差或出现极限环振荡；由于传统的PID 控制很难解决伺服系统中的非线性问题，因而不能适用于高精度、超低速伺服系统；本文通过引入模糊自适应整定PID控制，利用模糊规则在线调整比例、积分、微分环节，使系统具有一定的智能，从而非常明显的改善伺服系统的静态及动态性能。
