【摘要】 由于各执行元件泄漏、负载和性能的差异及制造误差,多执行机构会产生同步误差。结合比例伺服阀的特点,建立非对称动力机构的数学模型,并对比例伺服阀进行建模分析,最终建立阀控四缸同步控制系统的数学模型。
【Abstract】 Due to the difference of leakage,load and characteristics of actuators,and error in manufacture,the synchronization error is inevitable in multi-actuators’ movement.Establishes the mathematical model of asymmetrical actuators with considering characteristic of proportional servo-valve,analyzes the modeling of proportional servo-valve,and finally sets up the mathematical model of valve controlled 4-cylinder synchronous control system.
【Key words】 synchronous control; proportional servo-valve; hydraulic support test-bed; mathematical model;
