摘要
为了用模拟电压控制直流电机,设计了一种模拟直流脉宽调制(PWM)电机功率放大器。为了补偿机电控制系统中常见的库仑摩擦力,利用加法电路从硬件上实现了库仑摩擦力补偿。试验表明,补偿效果良好,值得推广。
For purpose of using analog voltage to control DC motor,a analog PWM DC motor driver was designed. Adding circuit was used to compensate coulomb friction which commonly exists among many mechanical electrical control system. Experimental results showed that compensation effect was good,should be promoted.
