Time response analysis

The system with the open loop transfer function 1/s(1+s) is:

• Type 2 and order 1

• Type 1 and order 1

• Type 0 and order 0

• Type 1 and order 2

How can the steady state error can be reduced?

• By decreasing the type of the system

• By increasing system gain

• By decreasing the static error constant

• By increasing the input

Transient response analysis is done for_________ systems.

• Unstable

• Stable

• Conditionally stable

• Marginally stable

Standard test signals in control system are:

• Impulse signal

• Ramp signal

• Unit step signal

• All of the mentioned

Ramp input :

• Denotes constant velocity

• Value increases linearly with time

• It denotes constant velocity and varies linearly with time

• It varies exponentially with time

Laplace transform of unit impulse signal is :

• A/s

• A

• 1

• 1/s

Which of the following transfer function will have the greatest maximum overshoot?

• 9/(s^2+2s+9)

• 16/(s^2+2s+16)

• 25/(s^2+2s+25)

• 36/(s^2+2s+36)

The damping ratio and peak overshoot are measures of:

• Relative stability

• Speed of response

• Steady state error

• Absolute stability

Find the type and order of the system given below:

• type 2,order 3

• type 2,order 2

• type 3,order 3

• None of the mentioned

Consider a system with transfer function G(s) = s+6/Ks2+s+6. Its damping ratio will be 0.5 when the values of k is:

• 2/6

• 3

• 1/6

• 6
