Research on locating control method of ball mill based on prediction

To solve the difficulty of precise locating of large inertia ball mill, a new method based on prediction is put forward. The feasibility of this method was analyzed using the motor theory and analysis on the ball mill kinematics and dynamics. The equipment to install rotary encoder that was connected to the ball mill was designed. And the testing hard ware based on single-chip microcomputer was build, and data of the angle and the rotational speed of the ball mill were acquired. With the tool of Mat lab, data were analyzed. The results shows that the angle predicted from the starting stage is very much closed to the angle which is measured, and the tolerance is very small, and it can meet the application completely.
