Consider the following first-order plus dead-time process: Y(s) U(s) = 2.4e-3s 5s +1 Design a PI controller for disturbance rejection for this process using: 1. The Cohen-Coon correlations 2. The Ciancone correlations 3. The ITAE correlations 4. The Ziegler-Nichols method (this will require a bode plot) The disturbance transfer function for this process is: Y(s) D(s) -3.7 3.5s + 1 5. Simulate this system responding to a step change in D(s) while under closed-loop Pl control via the controllers found via various schemes. Comment on the results. 6. Consider now the situation where there are sensor dynamics and the error sent to the controller block is computed as the difference between the reference signal R(s) and the error: YM(S) Y(s) 0.8 = s+1 E(S) = R(S) - Yм(s) 7. Simulate this system under closed-loop Pl feedback control with this new information. What effect does it have on the controller performance? Which control structure performs best now that new dynamics are introduced, and why?

Write python program to plot the zeros and poles if a user provides the coefficients for the numerator and denominator of the transfer function. Since the zeros and poles can be complex, this plot is essentially and argand diagram, where the x axis is the real component and the y axis the imaginary component of a given zero or pole. Create a method called plot-poles zeros(num, den) which takes two lists containing the coefficients. Here is an example and the resulting plot. num [1, 3, 7] # yields zeros at -1.5 +/- 2.17945j den = [1, 4, 5, 3] # yields poles at -2.46557, -0.7672143 +/- 0.7925519j plot_poles_zeros(num, den) Imaginary Page 2 Pole-Zero Plot 3 Zeros × Poles 2 1 -2 1 * Real When you write your code you are only allowed to use the packages numpy and matplotlib.
