Method and device for controlling cantilever crane, controller and engineering machinery
The invention discloses a method and device for controlling a cantilever crane, a controller and engineering machinery. The method comprises the steps that under the condition that a movement instruction signal is received, the target position of a joint is determined according to the movement instruction signal, and the initial valve control amount of a control valve is determined according to the current position and the target position of the joint. And the actual temperature of hydraulic oil in the hydraulic cylinder is obtained, and under the condition that the actual temperature is larger than the preset temperature, the compensation valve control amount of the control valve is determined according to the actual temperature. And according to the initial valve control amount and the compensation valve control amount, the target valve control amount of the control valve is determined, and the target valve control amount is used for controlling the opening degree of the control valve so as to control movement of the boom. The valve control amount is corrected through the temperature, the pressure building time of the hydraulic cylinder can be shortened, the joint response speed is guaranteed, the hydraulic system response is improved through control over the valve flow under different temperature working conditions, and therefore the boom control precision is improved.
本申请公开了一种用于控制臂架的方法、装置、控制器及工程机械。该方法包括：在接收到运动指令信号的情况下，根据运动指令信号确定关节的目标位置，根据关节的当前位置与目标位置，确定控制阀的初始阀控量。获取液压缸中的液压油的实际温度，在实际温度大于预设温度的情况下，根据实际温度确定控制阀的补偿阀控量。根据初始阀控量和补偿阀控量确定控制阀的目标阀控量，目标阀控量用于控制控制阀的开度，以控制臂架的运动。本申请通过温度修正阀控量，可以在不同温度工况下通过阀流量的控制，减小液压缸的建压时间、保证关节响应速度和提高液压系统响应，从而提高臂架控制精度。
