Problem 2 (50 points): Apply Routh's criterion to assess the number of unstable poles on the following transfer functions: 1. G(s) = 54+253 +252 +25+1 2. G(s) = 253 +52 +25+2 1 Verify your assessment by calculating the poles using the roots command in Matlab as shown before.

Routh's stability criterion is of limited usefulness in linear control systems analysis mainly because it does not suggest how to stabilize an unstable system. Thus, we should evaluate the stability range of a parameter value. Consider the servo system with tachometer feedback as shown in Figure 3(b). Evaluate the ranges of stability for K and Kn. (Note that Kn must be positive). R(s) C(s) 20 (5 + 1) (8 + 4) $ KA
