Consider a standard unity negative feedback control system with a phase-lead compensator Gc(s) and a plant G(s). Find the position of the centroid of the root-locus asymptotes. Pr your answer with 2 decimal point precision. G(s)=4(s-2.5)(s(s+6)2(s+6)(s+7)) Gc(s)=2(s+1.3)/(s+4)

For a negative unity feedback system. R(s) + where G(s) 5+1 s²+45+5 the poies of the closed loop system are QA1 and 4 B. None DC 2 and 3 OD A Of 1 and 4 E(s) G(s) C(s)

Suppose that one design specification for a feedback control system requires that the percent overshoot to a step input be less than 10%. The corresponding specification in the frequency domain is Select one: O a. Mp ≤ 0.55 O b. Mp 1.05 C. Mp ≤ 1.27 O d. Mp ≤ 0.59

10- A unity feedback system has open-loop transfer function G(s)=2/ (S+4), the ratio of time constants of open-loop to closed loop response will be: a- 1:1 b-2:1 c- 3:2 d-2:3 11-First column elements of the Routh's tabulation are 3, 5,-0.75, 0.5,2. It means that there: a- is one root in the left half of s-plane b- are two roots in the left half of s-plane c- are two roots in the right half of s-plane d- is one root in the right half of s-plane 12-An effect of phase-lag compensation on system performance is that: a-for a given relative stability, the velocity error constant is increased b- for a given relative stability, the velocity error constant is decreased c- the bandwidth of the system is increased d- the time response is made faster 13-The phase lead compensation is used to: a- increase rise time and decrease overshoot b- decrease both rise time and overshoot c- increase both rise time and overshoot d-decrease rise time and increase overshoot 14-When phase-lag compensation is…
