但是,矢量控制中需要进行使用三角函数的坐标变换,或复杂的计算处理。因此,大多情况下都会使用计算能力较强的微电脑作为控制用微电脑,比如配备了FPU(浮点运算器)的微电脑等。 下一章节,我们将使用瑞萨电子的开发套件“24V Motor Control Evaluation System for RX23T(俗称‘RSSK电机’)”,实际进行电机控制。
PWM可以用运算放大器IC模拟产生,也可以用微控制器数字产生。数字PWM发生器受PWM分辨率(PWM值变化的次数)的影响,例如,PWM的分辨率为8位,这意味着该PWM的变化值为256 (0-225),代表0%至100%的占空比。产生的PWM信号可以在图5中看到,PWM信号是通过比较DC信号中的电压控制信号(Vcontrol)和三角信号[10]中的锯齿信号...
