Boom control method and system
The invention discloses a boom control method and system. The boom control method comprises the steps that a preset angular velocity value for stretching or retracting a boom is input and a controller controls the stretching and retracting speed of a piston rod of an oil cylinder according to the preset angular velocity value and further comprises the steps that the real-time angular velocity value for stretching or retracting the boom is detected and compared with the preset angular velocity value; when the real-time angular velocity value is larger than the preset angular velocity value, the controller controls the stretching and retracting speed of the piston rod to be decreased; and when the real-time angular velocity value is smaller than the preset angular velocity value, the controller controls the stretching and retracting speed of the piston rod to be increased. After the preset angular velocity value is input, the real-time angular velocity value can be controlled to be close to the preset angular velocity value so that the boom can rotate at a constant speed, accordingly, the rotating speed of the boom is controlled stably and accurately, high operability is achieved, linear following of given input can be achieved, and rapid correction can be achieved even if under the influence of external factors.
