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.

working principle of washing machine:

washing machines running rpm is min 1000 to 1600 rpm that was runs principle of centrifugal force depends up on process next taken water inlet after completion of process of dirty removal from clothes and into outlet pipes is utilised and hence loaded clothes are rinse to dry that process has fully controlled with electrically. it has 4steps process.

soaking:when we load the clothes after fill the liquid in that and set the wchich type of clothes that are we fix the process mode and next that taken required level of water and soaked the clothes

Washing:wash the cloths after complete the certain time of soaking period,cloths moving with agiator drum with water,after complete the wash pump drains the water to outlet

Rinsing: After washing mode completion next step is rinsing,the process in pcb board has already fixed the programm of which duration we need depend upon cloth type rinsing is a 3 times do the process it is every 10min taken for each round

Drying:after removal of water, heat enters into exchange the moisture form dry type clothes after dry process will goes to end then door will unlocked position.

1.state flow

2.control logic of a washing machine

3.gear shifting

Results:

1.state flow diagram using problem solving of a sequentially.this type of program is like algorithm this is most important thing in programming.

2.this is working with logical sequence wise if any problem LED indicates of occurs error spring balance inbalanced the damper was noise so that program has working with sequencely.

3.A gear shift mechanism is a manual transmission includes a shaft ahially movable for selecting rated speed through changing gears.
