Week - 4

AIM:

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

Blocks used :-

• Toggle switch
• Constant
• Display
• Lamp
• Chart

TERMS USED :-

• u - power supply input
• v - water supply input
• exit - process complete

CHART :

1. Overview of system when both power and water supply off.

2. Overview of system when power supply on and water supply off.

3. Overview of system when power supply on and water supply ON and run for 600 sec.

4.Overview of system when power supply on and water supply ON and run for 350 sec.

Question 2:

Aim :

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.

Overview of arragement :-

Scope : change in speed

Scope result : change in gear
