    QUICK UPVOTE: As a control system engineer you have been asked to design a controller that would improve the error and the transient response for the unity feedback system below. The proposed solution must be cost-effective, so consider a passive network-based compensator. The transient response of the closed-loop transfer function to a ramp input has a 30% overshoot (%OS = 30) and a settling time Ts= 2.73 seconds. You need to decrease the peak time by a factor of 2,...

    6. At the local nuclear power plant, your boss wants you to use the Ziegler Nichols ultimate gain approach to design a PID controller. For some reason though, he doesn't want you to hook up a feedback loop and find the gain that results in marginal stability.
