Chapter 6, Problem 6.41(choose chapter or problem)
The frequency response of a plant in a unity feedback configuration is sketched in Fig. 6.101. Assume that the plant is open-loop stable and minimum-phase. (a) What is the velocity constant Kv for the system as drawn? (b) What is the damping ratio of the complex poles at = 100? Figure 6.101 Magnitude frequency response for 6.41 (c) Approximately what is the system error in tracking (following) a sinusoidal input of = 3 rad/sec? (d) What is the PM of the system as drawn? (Estimate to within 10.)
