Match List- I (Laplace transforms) with List - II (Time functions) and select the correct answer using the codes aiven below the lists:
A standard signal used for comparison in a closed-loop control system is called the
The difference between the output response and the reference signal is known as the _____ signal.
The Laplace transform of unity function is
The laplace transform of unity function i.e.
The phenomena of ‘limit cycles’ and ‘jump resonance’ are observed in
The Laplace transform of e-2t sin 3ωt is
Here, a = 2 and b = 3ω
A control system is said to be robust when
Which of the following is not correctly matched?
(CLCS = Closed Loop Control System and OLCS = Open Loop Control System)
Which of the following is not true regarding an open loop control system?
The effect of parameter variation and internal noise is more in an open loop system.
As compared to an open loop control system, a closed loop control system
The advantages of a closed-loop system (with feedback)
i) Improved sensitivity performance (the system is lesser sensitive to parameter variations)
ii) The bandwidth of the system increases.
iii) Effect of internal disturbances reduces.
speed ∝ bandwidth
The disadvantages are
i) Reduced gain – gain reduces by a factor 1 + GH
ii) The system can be unstable.
