说明：  悬挂轨迹控制系统是一电机控制系统，控制物体在80cm×100cm 的范围内作 直线、圆、寻迹等运动，并且在运动时能显示运动物体的坐标。设计采用AT89S5 1 单片机作为核心器件实现对物体运动轨迹的自动控制，通过多圈电位器实现对悬挂 物位置的精确测量，并引入局部闭环反馈控制环节对误差进行修正。以达到对物体 的控制和对坐标点的准确定位。采用脉冲宽度调制技术控制直流电机驱动芯片 L298 ，以实现对电机的转速、转向、启停等多种工作状态进行快速而准确的控制。
(Flying trajectory control system is a motor control system, control of 80cm × 100cm objects in the framework of linear, round, tracing movements and so on, and exercise can display the coordinates of moving objects. AT89S5 1 single-chip design as a core device for automatic control of trajectories of objects through the realization of multi-turn potentiometers for accurate measurement of the location of悬挂物and the introduction of local links of the closed-loop feedback control of the error be amended. In order to achieve the object of control and accurate positioning coordinates. Using pulse width modulation technique to control DC motor driver IC L298, in order to achieve the speed of the motor, shift, start and stop a variety of working conditions, such as rapid and accurate control.)
