Week - 4

Aim:

TO implement control logic of a Washing Machine uing Stateflow

Make a simulink chart for the Gear shift using stateflow

Q1:

In simulink implement the control logic of a Washing Machine using stateflow as per given input conditions,

creae a model and operate the model logic system an output an results

Explanation:

Provides a graphical languages are Flowcharts ,state transition tables and truth tables by using MATLAB

A washing Machine has fully automatic an using the on of physical signals

The stateflow is a simulink tool to implement the model, the inputs are

If the power supply is available, the system gets activated

If the Water supply is not available, stop the process & indicate through LED

Soaking time should be 200s followed by Washing time of 100s.

Then rinsing happens for next 20s & dryer runs for 50s

Chart:

Given the input values for turning ON an OFF the power supply and water supply.

VALUE=1 power and water turn ON condition

VALUE=0 power an water turn OFF condition

Simulink:

The output is displayed an using the lamp is on an off(pink smile )

Q2:

Create a modle for gear shifting logic as per given conditions given the speed input while simulation is running

Explanation:

It us a mechanical device that enable the driver to engage gears in obtain as the transmission retio called gear shifting

The Given conditions are;

Speed Range(kmph) Gear

0 to 15 1

16 to 25 2

26 to 40 3

41 to 60 4

Above 61 5

Chart:

The connections are slindre gain is acting a speedometer in running time

Create the constant and giving value 1 and 0 for ON an OFF

Cerate the lamp to indicate the power ON an OFF (pink smile symbel)

The mouste impartant of gear position display block

Simulink:

Result:

Q1;Thus the control logic of a washing machine using stateflow is processed as per the given sequence and pink LED

lights are turns to the green colour and the system is completed.

Q2; Simulink model is created for the gear shift logic and using the value is obtained.
