Week - 4

1.Aim: To implement contol logic of a washing machine usinf state flow simulink.

Objective:

• To implement the coontrol logic of a washing machiine using stateflow
• If the power supply is available the syste gets activated.
• If the water is not available stop the process and indicate through LED.
• soaking time should be 200 sec followd by wshing time of 100 sec.
• then rinsing happens for next 20 sec and dryer for 50 sec.
• After processes completed turn on the finished LED.

MODEL.:The file which contains the model is attached with this report.

• we have given WATER, SOAK, WASHING, RINSING,DRYER,CYCLE AS outputs of the chart.
• And WATER SUPPLY, POWER SUPPLLY is given as inputs.

SIMULATION PARAMETERS:

we have given 430 sec so that we can observe the whole cycle and sufficient time to store and solve parameters.

OUTPUT:

CONDITION 1: WHEN WATER SUPPLY IS OFF.

we turn off the water supply toggle switch and observe the output.

• observations are indicator of water is showing red i.e., when there is no water supply process is stopped and LED indicator is indicated.

CONDITION2:WHEN WATER AND POWER BOTH ARE TURNED ON .

• we can observe the all the states have been execMODEL:nd indicating the procees completion indicator shows green color.

CONCLUSION: THE SIMULATION OF WASHING MACHINE USING STATE FLOW IS DONE AND THE RESULT IS DONE AND SATISFACTORY.

2. AIM: TO make simulink chart chart for the gear shift logic.

OBJECTIVE :

Make a simulink chart for the gear shift for the below mentioned parameters.

GEAR SPEED RANGE (KMPH)

1 0TO15

2 16 TO 25

3 26 TO 40

4 41 TO 60

5 ABOVE 60

MODEL: The file which contains the model of GEAR SHIFT is attached with this report.

PARAMETERS: Here we give speed as an input for the chart.

we give speed as outut for the chart.

SIMULATION PARAMETERS:

we put time as infinity as inf, for our simulation run time until we stop.

INPUT: CONSTANT AND SLIDER GAIN ARE USED

slider is connected to chart as input. so changing the speed values from 0 to 100 during the simulation is running.

OUTPUT: The port of output chart is connected to only one display for each gear.

• BY giving the values in lamp such as 1,2,.. we can see the different lights in same switch according to gear shift byslider gain.

GEAR1:

speed range :0 to 15kmph.

input speed: 10 kpmh

color:YELLOW

GEAR2:

speed range:16 to 25kmph.

input speed : 20 kmph.

color:BROWN

GEAR3:

SPEED RANGE:26 to 40 kmph.

input speed 30 kmph.

color:PINK

GEAR4:

SPEED RANGE;41 to 60 kmph.

input speed 50 kmph

color:PURPLE

GEAR 5:

SPEED RANGE :ABOVE 60 kmph

input speed:80 kmph

color:GREEN

CONCLUSION:

THUS CREATED STATEFLOW FOR GEAR SHIFT BY USAING SIMULINK MODEL AND THE RESULTS AREFOUND AND WELL DONE.
