Root locus steady state error

WebThe two root loci are clearly very different, but it turns out (because of the way that I chose the systems) that if we choose K=40, we get two closed loop systems with identical … WebThe deviation of the output of control system from desired response during steady state is known as steady state error. It is represented as e s s. We can find steady state error …
