摘要
为了提高智能车的快速性和稳定性,必须精确检测车的速度,并有效控制车的速度;由此设计基于增量光电编码器速度检测脉冲四倍频器电路,以ATmegA128单片机为控制核心、MC33886PWM桥式功放为电机驱动器的速度控制系统;详细介绍了增量光电编码器及四倍频电路,控制器的环路、硬件构成、工作原理、控制策略、软件流程;最后提供了仿真数据、实验结论。通过实验可知,编码器应用得当、系统控制效果较好,能满足一般要求,从而验证了该方法理论的正确性和可行性。
For improving the rapidity and stability of smart car, it must accurately detect and effectively control the velocity of the car, so the article designs a speed controlling system based on the incremental photoelectric encoder velocity detection pulse frequency quadrupler circuit, which takes ATmegA128 microcontroller as control core and the MC33886PWM bridge power amplifier as the motor driver; it also introduces in details the incremental photoelectric encoder and frequency quadrupler circuit, loop of controller, hardware configuration, operating principle, control strategies and software processes, then it provides the simulation data and experimental con- clusion at the end. The result of experiments shows that the proper application of the encoder can get better system control effects so as to meet the general requirements, thus verify the correctness and feasibility of the method theoretically.
