Unformatted text preview: imaginary axis by constructing Routh array for each polynomial.
a) D(s) = s3 + s2 + 2s + 8 b) D(s) = s5 + 2s4 + 2s3 + 4s2 + 11s + 10 c) D(s) = s4 + s3 + 3s2 + 2s + 2 d) For parts a,b and c find the roots of the characteristic polynomial and indicate the roots that cause instability by using MATLAB.
Do not forget to add your MATLAB commands together with the outputs to your
homeworks. 1 Problem 2
Consider the system as shown in the figure a) Find the range of K that keeps the system stable. b) Find the value of K that makes the system marginally stable. c) Plot the response of the syste...
