Q

Output temperature can be converted to a
voltage by

A

Thermistor

17
Q

input position can be converted to a
voltage by

A

potentiometer or variable resistor

18
Q

the return path from the output to the
summing junction.

A

feedback
path

19
Q

output
signal is subtracted from the input signal

A

actuating signal

20
Q

that is,
the transducer amplifies its input by 1

A

Unity Gain

21
Q

the
actuating signal’s value is equal to the actual
difference between the input and the output.
Under this condition, the actuating signal is
called

A

error

22
Q

compensates for
disturbances by measuring the output response,
feeding that measurement back through a feedback
path, and comparing that response to the input at
the summing junction

A

Closed-loop System

23
Q

True or False?
Closed-loop systems, then, have the obvious
advantage of greater accuracy than open-loop
systems.

A

True

24
Q

True or False?

Transient response and steady-state error can be
controlled more conveniently and with greater
flexibility in closed-loop systems

A

True

25
Q

more
complex and expensive than open-loop systems

A

Closed-loop System

26
Q

These are also called
as non-feedback control
systems

A

Open-loop System

27
Q

Systems that do not have
this property of measurement and correction
are called

A

Open-loop System

28
Q

Classification of Control Systems

A

*Continuous time system
*Discrete-time system
*SISO System
*MIMO System

29
Q

control systems, all the signals are continuous in time

A

Continuous time system

30
Q

exists one or more discrete time signals.

A

Discrete-time System

31
Q

ontrol systems have one input and one output

A

Single Input and Single Output System

32
Q

control systems have more than one input and more
than one output.

A

Multiple input and multiple output system

33
Q

are able to transmit torque as well as
change rotation speed and direction from one gear
to the next

A

Gear

34
Q

is a direct measure of the ratio of the
rotational speeds of two or more interlocking gears

A

Gear Ratio
