【摘要】 轮胎耐久性试验机采用的是电液伺服系统,电液伺服系统属于本质非线性和不确定性系统,采用传统的经典模拟控制器难以取得好的控制效果。以ARM内核微处理器LPC2292为硬件核心,采用uc/os-Ⅱ嵌入式操作系统,运用模糊自整定PID控制算法实现试验过程的闭环压力控制,在现场应用中取得了很好的控制效果。更多还原

【Abstract】 Tire endurance testing machine adopt Electro-hydraulic servo system,Electro-hydraulic servo system is a Nonlinear and incertitude system,it can not get good control effect based on traditional simulate classical control.According to ARM kernel MPU LPC2292 as hardware core,adopt Embedded Operation System of uc/os-Ⅱ.Use fuzzy self adjust PID control arithmetic to achieve press control during the testing,it has been gotten good control effect at the scene.更多还原
