摘要:

系统采用单片机(STC89C54RD)作为主要控制器件,采用HEDS9701槽型光耦加360线光栅片组成的编码器获取帆板的角度信息,由单片机实时采集编码器的正交信号,从而获得实际角度。根据实际角度和目标角度数值,通过PID算法获得控制参量,调整PWM的参数,从而控制风扇转速,实现对帆板的角度修正和动态控制。

关键词: 单片机, 角度控制, PID

Abstract:

The system uses SCM (STC89C54RD) as the primary control device which can collect the quadrature signal of encoder in real time,and the encoder composed of HEDS9701 groove coupler and grating chip to obtain the angle information of the windsurfing,thus the actual angle.According to the actual and target angle values,the PID algorithm is adopted to obtain the control parameters and adjust the PWM parameters for controlling the fan speed,thus realizing the angle correction and dynamic control of the windsurfing.

Key words: SCM;angle control;PID
