Control Systems Objectives Part 01
01 . If torsional spring stiffness and reciprocal of capacitance are considered as analogous quantities the system being considered is torque-voltage
02 . Which of the following quantities under mechanical rotational system and electrical system are not analogous? Moment of inertia-conductance.
03 . The inverse Laplace transform of 1s+3 is e-3t
04 . When analogy is drawn between electrical systems and thermal systems, current is considered analogous to heat flow rate.
05 . For system shown in Fig. 18 (a) the analogous system is represented in Fig 18 (b) by figure A.
06 . The Laplace transform of damped sine wave e-at sinκt is κ(π+π)π+κπ .
07 . Under thermal and electrical system analogy, temperature is considered analogous to voltage.
08 . Mass in mechanical translational system is analogous to moment of inertia under mechanical rotational system.

12 . The Laplace transform of cosine wave is π¬ππ+κπ
13 . Charge air flow represents an analogous pair between electrical systems and pneumatic systems.
14 . Under force-current analogy, displacement is analogous to magnetic flux linkage.
15 . The inverse Laplace transform of 1s(s+2) ππ ππ [1-e-2t]
16 . It is generally preferred to draw analogies of non-electrical systems to electrical systems because electrical systems are more easily amenable to experimental study.

20 . Laplace transform of 1 is ππ¬.
