The invention relates to the field of mechanical engineering, in particular to a control method, a controller and a device for a crane boom and a crane. The method comprises the following steps: acquiring an expected speed and a first actual speed of the boom; determining a first speed deviation between the desired speed and a first actual speed; determining a first proportional control parameter for the current according to a preset mapping relation and the first speed deviation; the expected current is determined according to the first proportional control parameter; controlling an execution mechanism of the boom according to the expected current so as to determine the adjusted actual speed, and determining a second speed deviation between the expected speed and the adjusted actual speed; under the condition that the second speed deviation is smaller than the preset value, it is determined that the actual speed of the boom reaches the expected speed; and under the condition that the second speed deviation is greater than or equal to the preset value, taking the second speed deviation as the first speed deviation, and returning to the step of determining the first proportional control parameter for the current until the second speed deviation is less than the preset value.

    本申请涉及机械工程领域,具体地,涉及一种用于起重机臂架的控制方法、控制器、装置及起重机。方法包括:获取臂架的期望速度与第一实际速度;确定期望速度与第一实际速度之间的第一速度偏差;根据预设映射关系以及第一速度偏差确定针对电流的第一比例控制参数;并根据第一比例控制参数确定期望电流;从而根据期望电流控制臂架的执行机构,以确定调整后的实际速度,并确定期望速度与调整后的实际速度之间的第二速度偏差;在第二速度偏差小于预设值的情况下,确定臂架的实际速度达到期望速度;在第二速度偏差大于或等于预设值的情况下,将第二速度偏差作为第一速度偏差,并回到确定针对电流的第一比例控制参数的步骤,直到第二速度偏差小于预设值。
