The Design Of Electric Control System For Disc Mill

The design of electric control system for disc mill is introduced in this article; the system mainly includes the grinding mechanism of disc mill, automatic feeding closed loop control device with feeding velocity measurement and the drag control of main electromotor etc. States of disc mill and velocity of feeding motor can display in Chinese. Automatic feeding is the core of the electric control system that can communicate with PC.Apply automatic control theory and PID control method to generate a model for automatic feeding system, the model is analyzed in practice, simulation using MATLAB. Apply motor theory to analyze the drive of main motor, and propose a feasible program to start and brake.SCM AD89C51 is the core of the system, design peripheral circuits including input and output interface, display etc. Especially in automatic feeding control system, applying SCM to direct control stepper motor, position measurement, speed measurement etc. are key problems. Through analyzing the process of the system, design feasible program, frame control strategy and some soft procedures. According to work environment and complete machine situation, adopt anti-jamming measure etc.
