Top Ramp Input MCQ Objective Questions

Ramp Input Question 1:

In the system shown below, r(t)=1+2t,t>0

EE FT5 19

The steady state error will be

Answer (Detailed Solution Below) 0

Ramp Input Question 1 Detailed Solution

E(s)=R(s)C(s)=R(s)G(s)R(s)1+G(s)=R(s)1+G(s)R(s)=1s+2s2=s+2s2E(s)=s+2s2+10(s+1)(s+2)ess(t)=lims0sE(s)=0

Ramp Input Question 2:

The open loop transfer function of a unity feedback system is G(s)=Ks(s+4)(s+5). Determine the value of ‘K’ such that the steady state error due to unit ramp input is 0.4

  1. 25
  2. 50
  3. 75
  4. 100

Answer (Detailed Solution Below)

Option 2 : 50

Ramp Input Question 2 Detailed Solution

Given,

G(s)=Ks(s+4)(s+5) H(s) = 1

For ramp input ess=1Kv

Kv=lims0 s.G(s)=lims0 K(s+4)(s+5)=K20ess=20K=0.4K=50

Ramp Input Question 3:

The open loop transfer function of a system is given asG(s)=15Ks(1+5s). Find the minimum value of K such that the steady state error should not exceed 4 when the input rotates at 15 rpm.

  1. 1.5
  2. 3
  3. 4.5
  4. 6

Answer (Detailed Solution Below)

Option 1 : 1.5

Ramp Input Question 3 Detailed Solution

15rpm=15×2π60=πc2=90

Given ess<4,letinput=Ar(t)( type of system is 1)

But eSS=AKV=A15K  But A=15rpm=15×2πc60=πc2

ess<4×πc180

πc2×115K<4πc180

1K<46  K>1.5

 

Ramp Input Question 4:

Open loop transfer function of a unity feedback system is G(s)=500s(100+s)(1+s) Velocity error constant is

  1. 5
  2. 0
  3. 500

Answer (Detailed Solution Below)

Option 2 : 5

Ramp Input Question 4 Detailed Solution

Velocity error constant kv=lims0sG(s)H(s)

=lims0s.500s(s+1)(s+100)=5

Ramp Input Question 5:

The Bode asymptotic magnitude plot of a minimum phase system is shown in figure –

rename (5)

If the system is connected in unity negative feedback configuration the steady state error of closed loop system, to a unit ramp input is ______

Answer (Detailed Solution Below) 0.50

Ramp Input Question 5 Detailed Solution

The system is type – 1, since the initial slope is - 20 dB/Dec.

The Transfer function is given as , G(S)H(S)= K(1+S2)S(1+S10)

At ω = 2   ,   M = 0 dB hence

20log102+20log10K=0

K = 2

Steady state error for ramp input =1KV=12=0.5

Ramp Input Question 6:

For the series RLC circuit shown, the velocity error constant is

EC Control test 2 final Images (2marks)Q6

  1. 10

  2. 0.1

  3. 20

  4. 0.05

Answer (Detailed Solution Below)

Option 1 :

10

Ramp Input Question 6 Detailed Solution

TF=C(s)R(s)=1sCR+sL+1sCTF=1s2LC+sCR+1=1LCs2+(RL)s+1LC=G(s)H(s)1+G(s)H(s)

∴ open loop transfer function G(s)H(s)=1LCs2+RL.s

G(s)H(s)=1LCs(s+RL)

Velocity error constant KV=lts0s.G(s)H(s)

KV=lts01LC(s+RL)=1LC×LR=1RC=1100×103×106=10
