Week - 4

Q.1

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

SOLUTION:

stateflow of washing machine:

this is the systematic chart of washing machine

working of washing machine:The working principle of a washing machine is centrifugation. Centrifugation is a separation process that uses the action of centrifugal force to promote accelerated settling of particles in a solid-liquid mixture. The washing machine consists of a centrifuge for this purpose.

Q.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

solution:

Block use:

Slider

constant

lamp

switch

stateflow

when speed 15 kmph

(give input in slider and you will get the output)

when speed 25 kmph:

when speed 40 kmph:

when speed 60 kmph

when speed above 61:
