Week - 4

Aim:-

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

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.

#Solution1:-

Block used:-

1. Constant:- To give the input value.Give two constant one will be connected to the water and another is connected to the power.
2. Chart:- To set the control logic for Washing machine simulation.
3. Lamp:- The lamp is used to give the display a color that reflects an input value.
4. Display:- To give the output value.

Simulink Model:-

Output

1:- when both the water and power supply will be given.

The green indicate the model will ran through successfully.

2:- when either water and power are not provided.

The red light is glow the indicate the intruption the process.

Subsystem:-

This image shows the logic for the Washing machine phenomena.

Conclusion:-

1. The logical control of thr same machine could be executed as per required.
2. The real time changes in the simulation could also be observed if the simulation time is set to infinity.
3. More features could be added like different modes of washing.

#Solution 2:-

Block used:-

1. Constant:-To give the input gear range value.
2. Chart:- To set the control logic for gear shift simulation
3. Display:- To display the output value.

Simulink model:-

Subsystem:-

This image shows the logic for the gear shift phenomena.

Conclusion:-

1. Many automobile system could be designed according to the user with the help of state machine.
2. The above simulation is represent the real-time representation the vehicle's gear shift paradigm.
