The de motor is a very common and very important piece of hardware in many control systems. The dc servo is essentially a dc motor. When used in an "armature controlled" mode, the dc motor has the following transfer function (refer to p224 and p139, Ogata): 0,(s) V (8) K S(T s +1) where is the output position and Vis the voltage to the motor system. Time Response and Tacho Feedback Compensation Figure 1 shows the dc motor connected as...
