基于电阻屏的板球控制系统

A Cricket Controlling System Based on Resistive Screen

板球系统作为经典控制对象球杆系统的二维扩展,其实质上是把对小球位置的控制从直线延伸到平面,控制小球在平面内完成定位和轨迹跟踪。本系统采用位置式PID控制算法实现对小球的精准定位和轨迹跟踪,自主完成板球系统机械结构和控制电路的设计。通过上位机实时观测小球的响应曲线,对控制数据进行分析,反复调整PID参数,最终实现小球在平板上快速定位、稳定跟踪的目的。实验结果表明,该板球控制系统具有控制小球快速定位、精准轨迹跟踪的性能,以及较强的抗扰动能力。

As a two-dimensional extension of the classic control object“cue system”, cricket ball system essentially extends the control of the position of the ball from straight line to plane, and controls the ball to complete positioning and track tracking in the plane. This system uses the position PID control algorithm to realize the accurate positioning and trajectory tracking of the ball, and independently completes the design of the mechanical structure and control circuit of the cricket system. Through the real-time observation of the response curve of the ball by the upper computer, the control data is analyzed, and the PID parameters are adjusted repeatedly. Finally, the goal of rapid positioning and stable tracking of the ball on the plate is achieved. The experimental results show that the cricket ball control system has the properties of fast positioning, accurate trajectory tracking and strong anti-disturbance ability.
