摘要
阐述了利用FPGA技术设计悬挂运动控制系统的基本原理和系统架构。通过FPGA输出的具有时序的方波作为控制信号,信号经过芯片L298N驱动悬挂运动控制系统的步进电机。系统采用键盘输入对电机的状态进行控制,由LCD实时显示受控物体的位置。运用数学建模和逐次逼近的控制算法,以实现对物体运动轨迹的精确控制。系统在FPGA开发平台上设计并调试,经验证完全达到设计要求。
This paper elaborates the system construction and basic principle of suspensionsport control system which is designed by using FPGA technic. It takes the succession square - wave exported by FPGA as the control signal, which drives the stepping motor of handing movement control system when it passed the L298N chip. The system adopts the keyboard input to carry on the control to the stepping motor condition, and displays real - time position of controlled object by LCD. Mathematics modeling and gradual approaches control algorithm are used to actualize accuracy control to the object path. After the testing, the system which is designed and debugged on the FPGA platform meets the design requirements and the accurate control completely.
