State space model of a dc motor roroor L U Re Ry voor eh 0 rrrrrr Hilt K = 1.2 N-m/amp K = 1.2 V/(rad/sec) = 100 V/amp The figure above, show a control scheme for controlling the azimuth angle of a rotating antenna. The plant consists of an armature-controlled dc motor with dc generator used as an amplifier. The parameters of the plant are given below: Motor torque constant, Motor back emf constant, Generator gain constant, Motor to load gear ratio, J.B n = (0/0) = 1/2 Rf = 21 22, L = 5H, Rg = 9 22, Lg = 0.06 H, R = 102, L= 0.04 H, J=1.6 N-m/(rad/sec), B = 0.04 N-m/(rad/sec), Neglect the inertia and friction of the motor, taking physically meaningful and measurable variables as state variables, derive a state model for the system
