Week - 4

Aim:-

Implementing control logic of "Washing Machine" using stateflow.

• When power supply is available the system get activated.
• And when power supply is not available showing it through LED.
• Soakin time is 200s and washing time is 100s.
• After that rinsing for 20s and drying for 50s.
• After completing process turn on the finish light.

Control logic:-

• To input is applied one for power supply and other for water supply.
• Two constant block through which input is fed and controlled through slider switch.
• Input is provided to the chart which is enclosed operation.
• 0 is set for off condition and 1 is for on condition for both.

• In output 6 display connected for every operation and further connected to Lamp to show on/off conditions.
• Every display is assign for works like power supply, drying, ransing etc.
• In the flow chart logically work is assign.
• If the power is on and water is on it will further go for soaking, washing, rinsing and drying for time 200s, 100s, 20s, 50s respectively.
• If any of the water or power supply is off it will directly command to end.

• Symbols and through arrow the procedure is assign.
• Symbols has been given for every work.

Result:-

• When any of the power supply or water supply or both are off output will be OFF.
• When power supply and water supply is ON, first it will run 200s for soaking.
• After that it will run for 100s for washing.
• And further it will run 20s for ransing and 50s for drying.
• After all the procedure it will come to end.

2)

Aim:-

Simulink chart for Gear shift for given conditions.

Given:-

Speed in range(kmh)	0 to 15	16 to 25	26 to 40	41 to 60	61 and above
Gear	1	2	3	4	5

Control logic:-

• Constant input which is connected to slider assigned as speed range.
• Speed range is input speed which is connected to chart.
• Two display are connected to the output of chart named g and os.
• Which is further connected to Lamp.

• Symbols are given for input as speed range and output as g and os.

• Insied chart the logic is given for speed range as given below and accordingly assign gear number.

Speed in range(kmh)	0 to 15	16 to 25	26 to 40	41 to 60	61 and above
Gear	1	2	3	4	5

Result:-

• As the speed increses accordingly gear changes.

When speed is 10

When speed is 24

When speed is 37

When speed is 55

when speed is 64
