本系统通过对直流小风扇风速的调节实现对风板转角的控制，使风板转角能够随风速变化而改变，且能快速达到设定角度并稳定。IAP15F2K61S2单片机为控制核心，通过键盘设定风板板角度 1602实时显示风板当前角度。单片机输出PWM波控制风扇的风速，通过GY521mpu-6050测量风板的倾角反馈至单片机，采用PID控制经典算法，使系统实现精确控制，然后微调小风扇的转速改变风速的大小使风板角度达到稳定。最终实现在悬挂重物的情况下风板能达到设定角度控制，且最终绝对值误差不超过5度.(The system realizes the control of the wind board angle through the regulation of the wind speed of the DC small fan, so that the angle of the wind plate can change with the speed of the wind, and can reach the setting angle quickly and stably. IAP15F2K61S2 single chip microcomputer for the control of the core, through the keyboard set board angle, 1602 real-time display of the current angle of the wind board. The wind speed output PWM wave control MCU fan, through the GY521mpu-6050 angle measurement of wind plate feedback to the microcontroller, using PID control algorithm to make the system achieve precise control, then fine tune small fan speed change the wind speed of the size of the wind angle stable plate. Finally, in the case of heavy loads, the wind power panel can achieve the set angle control, and the final absolute error is not more than 5 degrees)
