Week - 4

1. 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 & 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 Logic preparation Using reference from requirement logic sequence was created like below:

By connecting outputs to respective lamps we can get the led status like below:

Soak phase:

wash phase:

rinse phase

dry phase :

End:

power error:

water error:

Note: The lightning pattern is taken from whirlpool top load washing UI functionality.

2. Make a Simulink chart for the “Gear shift” logic as per below conditions:

Speed Range(kmph) Gear

0 to 15 1

16 to 25 2

26 to 40 3

41 to 60 4

Above 61 5

Give speed input while the simulation is running & display the gear number.

Programm:

Using signal builder reference speed wrt time was created

Logic created using switch case pattern as per requirement like below:

Display result:

Hence gearshit logic created using stateflow$
