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

After all the processes have completed turn on the finished LED

The working principle of the washing machine is centrifugation. Centrifugal force is a force on a body moving in a circular path and is directed away from the centre. The centrifugal force caused by spinning the clothes at around 800-1200 rpm.

• If the power supply is available, the system gets activated

- When the Power Supply is on all the LEDs will blink Constantly

• 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

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.

Components :

• Chart
• Display
• Constant
• Lamp
• Rocker Switch
• Slider

At Speed 72 kmph

At speed 72kmph which is above 61kmph gear 5 is implemented and Gear_fifth LED is glow Blue and display output as 1.

At speed 20 kmph

At speed 20kmph which is above 16kmph gear 2 is implemented and Gear_second LED is glow Blue and display output as 1.

At Speed 48 kmph

At speed 48kmph which is above 40kmph gear 4 is implemented and Gear_fourth LED is glow Blue and display output as 1

Conclusion :

Thus all condition simulated through stateflow chart successfully.
