A DC chopper is used in regenerative braking mode of a dc series motor. The dc supply is 600 V, the duty cycle is 70%. The average value of armature current is 100 A. It is continuous and ripple free. What is the value of power feedback to the supply ?
I want to represent each point on the graph paper with its corresponding scale written alongside it.
P5.10 A speed control system of an armature-controlled DC motor uses the back emf voltage of the motor as a feedback signal. (a) Draw the block diagram of this system (see Equation 2.66). (b) Calculate the steady- state error of this system to a step input command set- ting the speed to a new level. Assume that R, = L. = J = b = 1, the motor constant is Km = 1, and K, = 1. (c) Select a feedback gain for the back emf signal to yield a step response with an overshoot of 15%. %3!
