Question: From Figure Q1.2 determine the plant transfer function G ( s ) if an extra gain factor in the numerator of G(s) is 5 (10)

 From Figure Q1.2 determine the plant transfer function G(s) if an

From Figure Q1.2 determine the plant transfer function G(s) if an extra gain factor in the numerator of G(s) is 5(10)+1,

If the controller is a simple gain factor K, determine using Figure Q1.2 the range of proportional controller gains for which the system will remain stable in the closed-loop operation. You must explain how you calculated your result.

A plant of transfer function (s) is to be operated in closed-loop, with unity negative feedback, and a controller in the forward path as shown in Figure 21.1. R >+ E 1 controller G(S) Figure Q1.1 The root-locus of this system is shown in Figure Q1.2, when the controller is a simple gain factor K. Root Locus 5 4 2 N Imaginary Axis 2. 2 -3 -4 -5 -20 -15 0 5 -10 -5 Real Axis Figure Q1.2
