摘要
介绍了一种以高速单片机C8051F020为核心的移动机器人控制系统,阐述了PWM控制原理、硬件设计、实验结果及分析。系统驱动电路采用双极性H桥电路,通过改变电压极性及脉冲宽度调制波(PWM)的值,调整机器人行走方向和速度。实践表明,电路设计方式科学合理,系统对场地适应性强、成本低、实用性强。
This paper introduces a mobile robot control system which is constituted by a high speed single-chip C8051F021. It describes the PWM control principle, the hardware design, test result and analysis. The system uses ambipolar H-bridge as the drive circuit and adjusts the direction and speed of people by changing voltage polarity and value of PWM. The practice indicates that the design of the circuit is reasonable and is fewer requests for the ground with advantages of strong adaptability, low cost and strong practicability.
