Question 1

consist of subsystem and processes (or
plants) assembled for the purpose of controlling the
output of the processes.

Answer 1

control system

Question 2

A radar antenna positioned by the lower power
rotation of a knob at the input, requires a large
amount of power for its output rotation.

Answer 2

power amplification

Question 3

Robots designed by control system principles
can compensate for human disabilities.

Answer 3

robot system

Question 4

Is the stimulus or command applied to a
control system

Answer 4

input

Question 5

The actual response obtained from a
control system

Answer 5

output

Question 6

the
system controlled by the feedback control
system.

Answer 6

plant

Question 7

plant, under the control of the feedback control
system

Answer 7

controlled output

Question 8

is the transmission path from
the summing point to the controlled output c

Answer 8

forward path

Question 9

Typically
includes controllers, compensators, amplifiers.

Answer 9
