摘　　要：文章以DSP数字信号处理器为主控制芯片,同时针对本系统的非线性时变特征,设计出了模糊参数自适应PID控制器,开发出一套新的电液伺服控制系统。利用Fuzzy参数自适应PID控制器在不需要精确数学模型的条件下具有更快的响应和更小的超调。降低了控制系统的研制成本,提高了试验精度,扩大了试验机的使用范围,并为DSP在自控领域的应用提供了依据和参考。This paper presents a method to develop a new electro-hydraulic Servo control system, which is based on a new digital signal processor （DSP） controller and the fuzzy adaptive PID controller through analyzing the non-linear and time-variable character of the system. The fuzzy adaptive PID controller has faster response and less overshoot without exact mathematical model. The cost of the control system is decreased while the accuracy is improved,and the use field is more widely, It also provides a basis for the use of DSP in Automatic control field.
