Unformatted text preview: + a) Derive explicit formulae for AR and b) Determine the corner frequencies and asymptote slopes c) Sketch the corresponding Bode diagrams Problem 3: Consider the process: 5s e G(s) (10s 1) = + . Develop PI and PID controllers using the Ziegler-Nichols controller tuning rules. Compare all controllers to each other using numerical simulations. Test and compare the performance of the two controllers for a unit step change in the input....
