WebThis set of Control Systems Multiple Choice Questions & Answers (MCQs) focuses on “Routh-Hurwitz Stability Criterion”. 1. Routh Hurwitz criterion gives: a) Number of roots in … WebSince there are no sign changes above the even polynomial, the remaining root is in the left half-plane. Therefore the system is marginally stable. We can use MATLAB to find the range of gain for stability by generating a loop, changing gain, and finding at what gain we obtain right-half-plane poles.
