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 50

Ans).

Washing Machine Control logic has bee modeled in MATLAB StateFlow domain with conditions given in requirement and extra features also implemented as shown in fig...

conditions in Chart are as follows

during run at one instant and can see LED colour for partical state of mode

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.

Ans).

Shifting gear according to the speed of the vehicle has been modeled and slider is provided to vary the speed and current gear is displyed as shown in fig..

also we can see the gear number at 28.27kmph the gear number is 3 acording to requirement and it showed properly

logics are implemented through stateflow as shown below
