Week - 4

Ans 1:

AIM: To control the working of Washing M/C.

Given Condition:

• 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

Solution:

The block diagram for such cases are as follows:

Notification for Power Supply and Water Supply:

1: Flow is ON

2: Flows is OFF

Colour notification regarding the LED lamp:

For Operation LED:

Operation ON: Green

Operation OFF: Red

For Finished LED:

Operation Not Started: Grey

Operation ON: Green

Operation Finished: Red

The Washing M/C Configuration are as follows:

Ans 2:

AIM: To make a Simulink chart for gear shift

Given:

Speed Range(kmph) Gear

0 to 15 1

16 to 25 2

26 to 40 3

41 to 60 4

Above 61 5

The required block diagram for such problem are as follow:

To define above value we have use the repeating sequence block as speed input as shown below

The stateflow diagram for such condition are as follow:

And, the final result of such problem are as follows:
