摘要
控制电机运动,例如转向、速度、角度的控制,是单片机在机电控制中的一个典型应用。本设计以AT89C52单片机为核心,以4×4矩阵键盘做为输入达到控制直流电机的启停、速度和方向。在设计中,采用了PWM控制技术对电机进行过程控制,通过对占空比的计算达到精确调速的目的。
Control electric motor motion,for example vergence, speed,the angle controlling, be that the monolithic machine applies to electromechanical a model in controlling.Originally,design that the monolithic machine is core with AT89C52,compose with 4×4 matrix keyboards to be speed and direction import opening reaching the electric motor controlling direct-current staying.Before the PWM technology having designed middle,having adopted control to electric motor go along, by achieving accurate tune is fast purpose to the calculation taking up the empty space ratio.
