ABSTRACT
The system uses STC12C5A60S2 microcontroller as the core of the control system; tablet rotation to the stepper motor control, to L298 motor driver chip; rotary encoder modules for the angle sensor to monitor the tilt angle of the flat, and flat-panel liquid crystal display 1602 shows the tilt angle data is then sent to the microcontroller, microcontroller based on the collected angle changes, the PID algorithm to find the tablet angle of rotation, the tilt angle of the tablet happens to meet the force of the tablet on the coins in the horizontal directionthe weight is just to provide the force required by the lateral acceleration of the coin then STC12C5A60S2 microcontroller according to the minimum step angle of the stepper motor to precisely control the stepper motor rotates the corresponding number of steps in order to achieve control of the tablet to maintain equilibrium in the rotation system layout is basically rational, the actual operation is relatively stable, high control accuracy.
Key words: single chip STC12C5A60S2; free pendulum; stepping motor; the rotary encoder

引言
由于转子不平衡而引起的旋转机械振动是一类常见故障,其排除方法是进行动平衡[1].根据经典动平衡方法,无论是使用专用动平衡机亦或现场整机动平衡,,现代工业日趋流程化、一体化,各流程之间紧密祸合,、化工、冶金、电力等行业中尤为突出.
