摘　　要：设计并实现了一个帆板自动控制系统。以32位ARM微控制器LM3S811为控制核心,在设定的模式和间距(风扇与帆板之间的距离)下,对帆板转角的控制进行了实验分析与讨论。实验中采用PWM技术和PID控制器来调节风扇风力的大小,从而实现对帆板转角的实时控制。整个系统软硬件设计合理、操作简单方便,控制精度较高。实验结果进一步验证了设计方案的正确性,证实了所设计的系统具有一定的理论研究意义和实用性。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.
