Week - 4

AIM:-

Make a simulate the process of washing machine with given condition.

OBJECTIVE:-

Implement control logic of a ''Washing machine'' using ''Stateflow''as per given

Sequence:

• If the power supply is available, the system gets activated.
• If the water supply is not available stop the process and indicate the LED.
• Soaking time should 200s followed by washing machine time of 100s.
• Then rinsing happen for next 20s & dryer runs for 50s.
• After all the processes have completed turn on the finished LED.

CHART DIAGRAM:-

PARAMETER:

we have a given water,soak,waching,rising,dryer,cycle as output of the chart.

we have given water_supply & power_supply as input of the chart.

OUTPUT:-

There are two condition asked to solve in the equation.

CONDITION:-1

When water supply is OFF.

We should not provide water supply and check for output

Implementing control logic of a "washing machine" using state flow

from the above diagram,we can see that indiactor of Water is showing Red i.e; when there is no water

supply the process is terminated and LED TERMINATED is used to indicate that state .

CONDITION:-2

When the water supplyis ON

Now we are providing the water supply and check the output ,

Implementing control logic of a "washing machine" using state flow

As we can observ from the above figure,all states have been executed and indicating the process completion

indicator (named as cycle) showing GREEN.

CONCLUSION:-

• The simulation of the washing machine using state flow is done and the result is satisfactory

TASK:2

AIM:-

To make a simulink chart for the ''Gear shift''logic.

OBJECTIVE:-

Making a simulink chart for the Gear shift for below mentioned

Speed Range (kmph) Gear

0 to 15 1

16 to 25 2

26 to 40 3

41 to 60 4

Above 61 5

CHART DIAGRAM:-

• Here we give speed as input for the chart.
• Here we give speed as output for the chart.

SIMULATION PARAMETER"-

Here we gave time as 'inf'for our simulation should run until we stop it.

OUTPUT:

The output produced is recorded when it's displayingthe each gear.

Gear:1-

Speed range :-0 to 15kmph.

Input speed :-10kmph.

Status- All display should be zero

Gear:2:-

Speed range:-16 to 25 kmph

Input speed: 20 kmph

Status-Gear1 ON

Gear:-3

Speed range:26 to 40 kmph.

Input speed-30 kmph

Status-Gear1 and Gear2 is ON

Gear-4:

Speed range:41 to 60 kmph

Input speed- 50 kmph

Status-Gear 1 Gear 2 Gear 3 is ON.

Gear-5:

Speed range:Above 60 kmph.

Input speed:80kmph.

Status-Gear 1 Gear 2 Gera 3 Gear 4 is ON.

CONCLUSION:-

• Created a state flow for gear shift using simulink and the resultare satisfactory.
