Position Control of Electro hydraulic Servo System for CNC Gear Grinder

针对电液伺服系统本身固有的非线性等特点，从提高低速运动性能的角度和系统的稳态定位精度出发，设计了一种模糊位置控制器。该方案可有效地达到设计指标要求。文章还给出了系统硬件的构成与具体实现。

Cosidering the inherent nonlinear kinematic characteristics of electro hydraulic position servo system, a fuzzy controller is designed in order to improve low speed performance and stationary positioning accuracy. The practical results show that this method can effectively meet the demand of design performance, the system hardware structure and actual realization are also introduced.
