A satellite attitude control system, as shown below, has a plant with transfer function $G(s)=\frac{1}{s^2}$ cascaded with a compensator $C(s)=\frac{K(s+α)}{s+4...

Consider an even polynomial p(s) given byp(s) = s4 + 5s2 + 4 + K,where K is an unknown real parameter. The complete range of K for which p(s) has all its roots...

The Nyquist stability criterion and the Routh criterion both are powerful analysis tools for determining the stability of feedback controllers. Identify which o...
