Question:

An uncompensated control system with unity feedback has a plant transfer function

We want to have a velocity error constant of Kv - 20. We also want to have a phase margin of approximately 45° and a closed-loop bandwidth greater than a) = 4 rad/s. Use two identical cascaded phase-lead networks to compensate the system.
