EV BATCH - 17

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

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

BLOCKS USED :

• Chart box
• Constant
• Display
• Lamp

Simulation model :

EXPLANATION :

1. First open the matlab and click on the simulink then we get the simulink blank model.
2. And click on the library select the chart block . Then double click on the chart block we go to inside the chart block .
3. Now take the blocks we want 9 blocks and give the connections as shown in the below figure.
4. And now give the names and give the conditions as shown in figure above .and then save the model .
5. Next go the modeling shown in above the model and select the symboles spane now get the symboles page on left side of the model . it like shown in the figure below .
6. Now select the input and outputs in the above figure . Here we give X & Y as inputs and remaining variables as ouputs .
7. Now we get out of the chart block after that we can see full blank model with two inputs and 7 ouputs .
8. Next go the library and select the required blockes i.e., constant, dispaly and lamp . In this we want two constants , 7 displays and 7 lamps .
9. Now connect the two constants to inputs of X & Y and then connect the dispalys to the ouputs . And then gives the naming the lamps and connect the lamps to the all respective displays . It is like as shown the figure below .

Now click on the water supply lamp and change the colour as your wish and then change the stop time as 700 and run the simulation .

Conditions :

1 . If the power supply is available, the system gets activated

Here we give the constant 2 as value of 1 and run the simulation we can see tha system will activated .

2 . If the Water supply is not available, stop the process & indicate through LED

Here we give constant 1 as value of 0 and then run the simulation we can see the whole system process was stop and water supply will golw .

3 . Here we give the Soaking time should be 200s followed by Washing time of 100s.

4 . And then rinsing happens for next 20s & dryer runs for 50s.

Conclusion : Here the implement of logic of washing machine is completed and here we can see all the given conditions are satisfied .

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.

AIM : Make a simulink chart for a "Gear shift" logic and satisfy the give conditions and aslo give the speed input while the simulation is running and display the gear number.

BLOCKS USED :

• Chart
• Constant
• Slider
• Display

SIMULATION MODEL :

EXPLANATION :

1 . First open the matlab and click on the simulink then we get the simulink blank model .

2 . Now go to the library select the chart block then double click on the chart block and then we go the inside of the chart block.

3 . Now take the chart . In this we want 5 chart and then give the nameing and give the conditons and connections as shown in the below figure.

4 . Now go the modeling shown the above of model blank and select the symboles spane . Then we get the symboles page and we give the Sas input and G as output as shown in the below figure .

5 . Now come out of the chart and we can see the full form of chart model with one input S and one output W .

6 . Next click on the library and select the required blockes i.e., constant , slider , and display . Now connect the constant to the input S of chart and connect the display to the output W of the chart and connect the slider to the constant as shown in the simulation model .

7 . Now vary values in the slider block and click on the run and we can see the results in the display .

CONDITIONS :

1 . IF THE SPEED RANGE IS BETWEEN 0 TO 15 (Kmph) THEN THE GEAR SHIFT WILL BE THE 1 .

2 . IF THE SPEED RANGE IS BETWEEN THE 16 TO 25 THEN THE GEAR SHIFT WILL BE 2 .

3 . IF THE SPEED RANGE IS BETWEEN 26 TO 40 (Kmph) THEN THE GEAR SHIFT WILL BE 3 .

4 . IF THE SPEED RANGE S BETWEEN 41 TO 60 (Kmph) THEN THE GEAR SHIFT WILL BE 4 .

5 . IF THE SPEED RANGE ABOVE 61 THEN THE GEAR SHIFT WILL BE 5 .

CONCLUSION : Here we make a simulink chart for the gear shift as followed by given 5 conditions are satisfied .
