2. Hi please below problem given in picture

Problem 2
The block diagram of an electric train control is shown in the figure below. The system
parameters are
• er(t) - voltage representing the desired train speed, V
• v(t) - speed of train, ft/sec
M-mass of train = 30000lb
•K-amplifier gain
• Kt - gain of speed indicator

To determine the transfer function of the controller, we apply a step function of 1 volt to
the input of the controller, that is, ec(t) = us(t). The output of the controller is measured
and described by the following equation:
100(1-0.3e-6t_ -0.1e-1⁰t)us(t)

Then
• Find the transfer function Gc(s) of the controller
V(s)
• Derive the forward path transfer function of the system. The feedback path is
opened in this case.
