Question

Thank you very much !

A field controlled DC machine with feedback is shown in Figure Q1. The machine drives a load with an inertia and a rotational friction coefficient B = 0.002Nm(rad/sec). The field winding has a resistance of 5 ohm and an inductance of an 0.2H. The armature current is constant and the machine produces 3Nm of torque per amp of field current. The shaft speed is measured by a tachometer whose output is 0.1 volts/( rad/s). The tachometer output is subtracted from a voltage reference and the voltage error amplified by an amplifier with a gain of A. Find a transfer function for each Block In the diagram. Derive an expression in terms of s and A for the closed loop transfer function of the system.
