P9. The forward transfer function of a unity feedback type 1, the second-order system, has a pole at (-2). The nature of gain K is so adjusted that the damping ratio is equal to 0.4, the input to the system is r(t) = 1+4t find ess.

A double delay line canceller with feedback is shown below, (a) what is the transfer function H(z), (b) plot the frequency response for K₁ = K₂ = 0. delay, T Ki delay, T

Given the system equipped with unitary feedback, whose direct branch transfer function is: Design a PID controller with one of the Ziegler-Nichols methods.

Calculate the poles, decay rate, damped natural frequency, undamped natural fre- quency, and damping ratio of the system represented by the transfer function below. State whether the system is overdamped, underdamped, undamped, critically damped, or unstable. -3 = s² + 4s + 4 G(s) =
