Week - 4

OBJECTIVES:

1. To implement control logic of a “washing machine” using State flow 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.

Objective 1:

The washing machine model designed is as shown below:

The state flow logic is as shown below:

The symbols or variables can be declared in the symbol pane as below:

Part 1: If the power supply is available, the system gets activated.

Part 2: If the Water supply is not available, stop the process & indicate through LED

Part 3: Soaking time should be 200s followed by Washing time of 100s.

Part 4:Then rinsing happens for next 20s & dryer runs for 50s

Part 5: After all the processes have completed turn on the finished LED

OBJECTIVE 2:

GEAR SHIFT LOGIC

The model diagram of Gear shift model is as shown below:
