【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。更多还原

【Abstract】 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.更多还原
