    • A system for the control of a fluid flow control valve (14) which controls the supply of fluid to an actuator (12) to control the movement of a component such as a tractor implement hitch (10,13) in response to a selected operating parameter such as hitch position or draft force. The system enables the desired value of the selected parameter to be set (S) and this desired value is compared (P,D)with the actual sensed value of the parameter to provide a parameter error signal (E) . A start-up control function (SUC) is provided to improve the initial speed of response of the system. The start-up control function is arranged on each detection of a parameter error signal to apply a start-up signal to the valve to initiate movement of the component and, if no movement results, to increase the start-up signal until movement of the component is detected (20,25) whereupon the increase in the start-up signal is stopped and the magnitude of the signal applied to the valve is dependent on the parameter error signal so as to tend to reduce the error signal to zero.
    • 一种用于控制流体流量控制阀(14)的系统,其控制向致动器(12)供应流体以响应于所选择的操作来控制诸如拖拉机实施装置(10,13)的部件的运动 参数如牵引位置或牵引力。 该系统使所选择的参数的期望值被设定(S),并将该期望值与参数的实际检测值进行比较(P,D)以提供参数误差信号(E)。 提供启动控制功能(SUC)以提高系统的初始响应速度。 启动控制功能被布置在对参数误差信号的每次检测上,以将起动信号施加到阀门以启动部件的移动,并且如果没有移动结果,则增加起动信号直到 检测到分量(20,25),由此停止启动信号的增加,并且施加到阀的信号的大小取决于参数误差信号,以便将误差信号减小到零。
