Draw and carefully and thoroughly label a block
diagram of an “open loop” control system.
Draw and carefully and thoroughly label a
block diagram of a “closed loop” control system.
Check whether the indicated
application is best represented by an open-loop or closed loop
control system model. If you think there is some
ambiguity, discuss as necessary.

Draw the cloed loop block diagram of Inverter AC. Explain the
working of the Inverter AC and briefly describe the working of each
component in the system. Suggest the components available in the
market to develop the system.
Draw block diagram of a sun tracking system for a solar power
system. Also mention the component clearly.
Note: give a small description of its
working.
Diagram and give a specific example of short-loop and long-loop
negative feedback in endocrine regulation. Describe the differences
in levels of each hormone in the pathway in response to a Primary
hypersecretion defect, and to both types of Secondary
hypersecretion defects (hypothalamic and pituitary).
Decide whether each of these statements is True (T) or False
(F).
A closed-loop control system:
(i) Has negative feedback.
(ii) Responds to changes in conditions.
1. (i) T (ii) T
2. (i) T (ii) F
3. (i) F (ii) T
4. (i) F (ii) F
7. Decide whether each of these statements is True (T) or False
(F).
A closed-loop control system:
(i) Has a measurement system which gives feedback of a signal which
is a measure of the...
