摘　　要：该文设计了一种基于瑞萨单片机控制的微型风力摆系统。系统采用基于微机电MEMS的重力加速度陀螺仪MPU6050采集风力摆姿态数据,通过IIC总线将数据实时传输到系统控制器瑞萨R5F100LGA单片机;经相应的控制算法处理后产生多路PWM信号驱动风力摆执行机构的轴流风机,完成风力摆运动的闭环控制。系统控制器实现了运动矢量分解和合成算法,采用PID控制器完成对风力摆运动轨迹的精确控制和姿态调整。此外系统采用了LCD液晶屏和矩阵键盘作为人机接口,实现风力摆系统控制参数的人机交互。此风力摆实现摆杆的快速起摆、直线摆动,并在此基础上具有摆幅可设、摆向可控、摆速制动、摆杆画圆和系统抗外界干扰等功能。In this paper,we design a micro wind pendulum based on MCU control system. The system uses MPU6050 based on micro electro mechanical MEMS to collect the attitude data of the wind pendulum,and through the IIC bus make real-time data transmission to the system controller Rui R5F100LGA MCU. After the corresponding control algorithm is processed,the multi channel PWM signal is used to drive the axial fan of the wind pendulum actuator to complete the closed-loop control of the wind pendulum motion. The system controller realizes the motion vector decomposition and synthesis algorithm,and uses the PID controller to achieve the precise control and attitude adjustment. In addition,the system uses the LCD screen and the matrix keyboard as the man-machine interface to realize the man-machine interaction. The wind swing realize the rapid and the pendulum swinging rod,linear oscillation,and On this basis,there are a lot of expanding function.
