| description | The invention discloses an intelligent PID (Proportion Integration Differentiation) controller, a control method and a system for a material weighing process of a high-pressure roller milling process. An intelligent PID controller in the material weight process of the high-pressure rolling process takes a material weight signal fed back by a material weight sensor arranged on a surge bin and a belt motor current signal fed back by a current sensor arranged on one side, close to the surge bin, of a belt conveyor as input, and outputs the frequency of a vibrating feeder; the first parameter of the PID controller is updated in real time according to the current working condition; the first parameters comprise a sampling period, a control output upper limit and a control output lower limit. According to the method, a conventional PID adjusting mode is changed by combining actual high-pressure roller abrasive heavy process characteristics based on working condition analysis, and parameters of a sampling period T, |
