1. Derive the plant transfer function, , for the DC motor position system in terms of the motor gain constant, K, and the time constant, τ.
2. Consider PD-Control with set-point weighting by setting ki = 0 in Equation 6.4.1.  Determine the closed-loop transfer function from the position reference, r, to the angular position output, θ in radians, i.e., Y(s)/R(s), in terms of K, τ, bsp, kp and kd.
3. Determine kp and kd in terms of the closed-loop natural frequency, ωn, damping ratio, ζ, motor time constant, τ, and motor gain constant, K.
4. Determine the steady-state error to a unit step input.  Given bsp = 1, determine the DC Gain of the closed-loop motor position system. help_outlineImage TranscriptionclosePre-Lab Reading The block diagram of the closed-loop system for control of motor position is shown in the figure.
