ECE 382 Homework 5 Due: Wednesday, February 3, 2010 1) An ECE 382 student is trying to design a unity negative feedback control system that will have an underdamped response to a step input. He/She came up with 4 different closed- loop poles for his/her systems. These locations are labeled (A) through (D) in the following figure with θ 1 = 70 and θ 2 = 40 . Tabulate the rise time, peak time, percentage maximum overshoot, and settling time for each of these 4 systems. Discuss your results and indicate where you would place the closed-loop poles (i.e., which pole location would you pick for your system if you are designing this system). 2 � � � � �� � �� � �� �

Unformatted text preview: 2) The following two systems have the same transfer function when K 1 = K 2 = 100. Com-pare the sensitivities of these two systems with respect to parameter K 1 for nominal values K 1 = K 2 = 100. 0.09 ∑ K 1 K 2 ∑ K 1 K 2 0.0099 R(s) + _ C(s) (a) + _ R(s) C(s) 0.09 ∑ _ (b) 3) Do the following problems in your 4th-edition textbook (pp. 331-332; see the attached). Problem B-5-9 and use MATLAB to plot all the requested curves. Problems B-5-10 and B-5-11 and use MATLAB to plot the output to see whether all the specifications are satisfied. Explain your MATLAB plots and attach them to your homework....
