Abstract
A self-adaptive control system comprises a feeding device, a rotary coder, a displacement sensor, a hydraulic regulation system and a controller, wherein, the input end of the controller is electrically connected with the rotary coder, the displacement sensor, a first oil pressure sensor and a second oil pressure sensor respectively, and the output end of the controller is electrically connected with a solenoid directional valve via an interlocking controller; the controller takes the bearing force of piston rods and the rotation speed and the rotation speed change rate of a feeding knife roller as input variables and takes the positions of the piston rods as an output variable, to establish a fuzzy control model of the feeding mouth opening of the feeding device, the extension and retraction of the piston rods in a left oil cylinder and a right oil cylinder under hydraulic driving are regulated actively by controlling a three-position four-way solenoid directional valve, and thereby self-adaptive control of the feeding mouth opening is achieved.
