Challenge

Week - 4

1) Implement control logic of a “washing machine” using Stateflow as per given sequence:

After all the processes have completed turn on the finished LED.

ANSWER:

Basically washing machine under goes four process,

1.Soaking

2.Washing

3.Rinsing

4.Drying

SIMULINK AND LOGIC OF WASHING MACHINE:

WORKING PROCESS:

In the above control logic first state is created with 2 conditions for power supply .
One is with power supply available(Power==1)and second with water supply available (Water==1).
If the power supply at entry is 1 and water supply is on, then machine will get activated and start the next process of operation.
Next 4 Operation states have been created in flow order Soaking,Washing,Rinsing,Drying with their time of operation as 200sec for a soak,100sec for wash,20sec for rinse & 50sec for dry.
Entry and exit condition of the state are kept as 1 & 0 & i.e at entry of operation states it is 1 and as operation completes it is 0 for every states.
After all process has done washing machine completed LED will glow and we can shut the machine off.

CONCLUSION:

Thus the simulink is created for washing machine logic and obtained the output result.

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.

ANSWER:

Gear shift logic is decided by the speed of the vehicle is used to decide the gear of the vehicle.

Simulink block diagram and chart of "Gear shift":

In the above block digram, slider gain is used to obtain the values for gear shift.

LOGIC OF GEAR SHIFT:

CONCLUSION:

By adjusting the slider gain i kept the value of 70.
The value 70 is greater than 60, therefore the car running on the 5th gear and the result is displayed.
Lamp of the 5th gear also glows green.
Thus the simulink is created for gear shift logic and obtained the output result.
