摘　　要：转阀式直接驱动电液伺服阀具有很大的优越性,但必须对其进行有效的控制.针对摩擦非线性比较严重,建立精确数学模型困难的情况,采用自整定模糊PID控制.介绍了设计过程,研制出针对转阀的模糊规则和合适的PID参数调整规律,最后通过数字仿真验证了该控制方法较强的抗干扰能力.Rotary type direct drive servo valve has great advantage,but it needs effective control.To the serious nonlinear friction and difficult to construct its mathematical model,the fuzzy PID control with parameter self-tuning is employed.Introduced the design process,developed the fuzzy rule and suitable PID parameter adjust law of rotary valve,in the end the digital simulation was done to verify this control method has strong ability to anti disturbance.
