Question 3-(40 pts) For the electric motor system in figure: motor resistance R - 102; the torque constant Km-IN m/ A and back-emf constant Kv=1V sec/ rad; the load shaft inertia J= 1 kg viscous friction coefficient b=IN m sec/ rad. The motor's own inertia and inductance are negligible. A) Derive the transfer function from v, to w (15 pts) B) Draw the velocity vs. time plot if v, is step control voltage of 5 volts, show the time constant and settling time on the plot. (10 pts) C) Draw a block diagram of the system if a negative feedback system is built with a tachometer (velocity) measurement from the motor with unit gain and an operational amplifier controller with gain K, where the amplifier output is vs. Find the closed loop transfer function (15pts).
