Compensators Q UESTION 23 For the closed–loop system in Figure 23 with and , complete the following: a. Sketch the Root Locus Diagram. Qualitatively describe the closed–loop system stability and transient characteristics for 0 < K < ∞. b. Calculate the value of K that achieves a steady–state error of 1 for r ( t ) = 8 t 2 . c. For the value of K calculated in part b and for r ( t ) = 8 t 2 , simulate the closed–loop system and plot y ( t ), e ( t ), and u ( t ). Turn in your Matlab code. G(s) KG C (s) U(s) R(s) + - Y(s) E(s) Figure 23 There is m = 1 finite open–loop zero located at –1 There are n = 3 finite open–loop poles located at 0, 0, and –2 There are n = 3 branches and n m = 2 branches go to infinity The Root Locus is on the real axis at 0 and from –1 to –2 The asymptote real–axis intercept is
