Hot rolling flying shear control method adopting ADRC (active disturbance rejection control) variable acceleration compensation

The invention belongs to the field of control engineering, and particularly relates to a hot rolling flying shear control method adopting ADRC (active disturbance rejection control) variable acceleration compensation. According to the method, an ADRC technology is mainly adopted to control the rotating speed of a flying shear in a variable acceleration compensation mode, and steel billets on a hot rolling production line are sheared. Firstly, a detection device is installed, the shearing length is calibrated, the linear speed of strip steel is detected in real time, and the walking perimeter of the equivalent radius of a flying shear blade and the distance value from a shearing point to the flying shear are equivalently solved; a speed set value of the flying shear blade is calculated according to the detection quantity; and finally, the speed of the shear blade is controlled by adopting an ADRC variable acceleration compensation control method according to the fluctuation change of the linear speed of the st
