Course Title: Feedback System Analysis and Design question
Electric and Electronics Engineering Feedback System Analysis and Design question.
There are 5 (Five) questions. Answer all the questions. Allocating marks are indicated in the right margin. Assume a reasonable value of any data if not provided. Unless otherwise stated, the symbols bear the usual meaning.
|Question Description||PO, CO||Bloom’s Level||Marks|
|1.||Classify stability. Find out the stability of the following system from the pole-zero plots and verify your findings from time-domain representations.
G(s) = (S + 2)
S 2 -15S + 56
|2.||Define Time constant, Rise time, Settling time, and Overshoot. Calculate peak value for a system that has 300% overshoot with unity steady-state/ final value.||PO 1,
|3.||Describe the rules of sketching root locus. Sketch the root locus for the
unity feedback system shown in the Figure 1 for G(s) = (s + 7)(s + 6)
(s – 4)(s -1)
|4.||Identify the transfer function, T (s) = C(s) for the signal flow graph in
|5.||A temperature control system operates by sensing the difference between the thermostat setting and the actual temperature and then opening a fuel valve an amount proportional to this difference. Sketch a functional closed-loop block diagram identifying the input and output transducers, the controller, and the plant. Further, identify the input and output signals of
all subsystems previously described.
