Definition
• Control System is an
interconnection of components
forming a system configuration that
will provide a desired system
response.
• There are two types of control
system.
a) Open Loop Control System
b) Close Loop Control System

Open Loop Control System
Defin ition
Open loop system :
Input Process Output
Definition :
• A system in which the control action is
totally independent of the output of the
system is known as open loop control
system.
• In Short “ An open loop control system is a
system that has no feedback system.”
• Example : Hair Drier, Washing Machine,
Celling Fan etc.

Electric Hand Dryer : Details :
• Hand dryers are electric machines that can not
work automatically. They may either operate
with the push of a button or automatically using
a sensor.
• Hot air (output) comes out as long as we keep
our hand under the machine, irrespective of how
much our hand is dried.

Automatic Washing Machine : Details :
• A washing machine is a home appliance
used to wash laundry. The term is mostly
applied to machines that use water as
opposed to dry cleaning or ultrasonic
cleaners. The user adds laundry detergent ,
which is sold in liquid or powder form, to
the wash water.
• This machine runs according to the pre-set
time irrespective of washing is completed or
not.

Bread Toaster : Details :
• A toaster is an electric small appliance
designed to expose various types of sliced
bread to radiant heat, browning the bread
so it becomes toast. The most common
household toasters are the pop-up
toaster and the toaster oven.
• This machine runs as per adjusted time
irrespective of toasting is completed or not.

Automatic Vending Machine : Details :
• A vending machine is an automated
machine that provides items such as snacks,
beverages and lottery tickets to consumers
after money, a credit card, or a specially
designed card is inserted into the machine.
• These machines produce a beverage from
the coffee bean itself. These machines also
function for pre adjusted time only. Then it’s
provide desired output as coffee.

Celling Fan : Details :
• A ceiling fan is a mechanical fan mounted on
the ceiling of a room or space, usually
electrically powered, suspended from the
ceiling of a room, that uses hub-mounted
rotating blades to circulate air. Ceiling fans
typically rotate more slowly than other
types of circulating fans, such as electric
desk fans.
• It is not also a self controlled machine. It can
regulate by manually control.

Analog Switch : Details :
• An analog switch acts like a solid-state relay.
Analog switches can also isolate devices at
their terminals when the analog switch is
OFF. When ON, they conduct both analog
and digital signals, regardless of the
direction in which the signal is traveling.
• Several semiconductor manufacturers offer
a variety of analog switches and have
selection guides that can help narrow down
to the best choice. As end it’s also used
open loop system.

Close Loop System : Definition :
• A system in which the control action is
somehow dependent on the output is
called as closed loop system.
• In Short “A system that has a feedback
system is called close loop system.”

Automatic Electric Iron : Details :
• An electric iron can be described as a small
hand-held appliance that is heated via
electricity to press clothes and removes
creases. Due to the heat and pressure of the
ironing plate, the fibers of the clothes get
stretched and attain a finished shape when
cool.
• Heating elements are controlled by output
temperature of the iron.

Servo Voltage Stabilizer : Details :
• Servo voltage stabilizer is a closed loop control
mechanism which serves to maintain balanced 3 or
single phase voltage output in spite of fluctuations at
the input owing to unbalanced conditions.
• A Servo Stabilizer is a Servo motor controlled
stabilization system that performs optimum voltage
supply using a Boost transformer booster that
captures voltage fluctuations from input and regulates
current to the correct output.
• Voltage controller operates depending upon output
voltage of the system.

Air Conditioner : Details :
• An air conditioner is a system or a machine
that treats air in a defined, usually enclosed
area via a refrigeration cycle in which
warm air is removed and replaced with
cooler air. In construction, a complete
system of heating, ventilation, and air
conditioning is referred to as HVAC.
• The air conditioner in a central heating and
cooling system provides cool air through
feedback system.

Water Level Controller : Details :
• A water level controller is a device that manages
water levels on a variety of systems such as
water tanks, pumps and swimming pools. The
basic function of a water level controller is to
regulate water flow and optimize system
performance.
• A water level indicator is a system that relays
information back to a control panel to indicate
whether a body of water has a high or low water
level. Some water level indicators use a
combination of probe sensors or float switches
to sense water levels.

Automatic Electric Oven : Details :
• An electric oven is a thermally insulated
chamber used for the heating, baking, or drying
of a substance. When anyone set the
temperature on the electric oven with either the
mechanical dial or electronic control, the bottom
heating element is activated. Electrical power
heats the wires, which in turn heats the metal
surrounding them. Convection ovens have a fan
to blow the hot air around inside the oven.
• A timer may allow the oven to be turned on and
off automatically at pre-set times. So, as a result
it’s work as a close loop system.
