| Abstract: | A certain sailboard control system is designed and realized in this paper. Based on the 32-bit LM3S811 ARM microcontroller, under the condition of the assumed pattern and space between the sailboard and the fan, a detailed experimental analysis and discussion are given for the control of the angle of the sailboard. In order to controt the angle of the sailboard, the wind power of the fan is modulated by using the pulse-width modulation （PWM）technique and the proportional-integral-derivative （PID）controller. The hardware and software of the whole system are designed reasonably, and the operation of the system is simple, convenient, and precise Experimental results prove that the design of the system has certain theoretical research significance and practicality. |
