Week - 4

Objective :

• Implimanation of control logic for " Washing machine " Using the provided State flow .
• implimentation Of the control logic for the " Gear Box " using the state flow provided .
• Checking and the validation if the system .

Conditions :

For Washing Machine :

• 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

For Gear Box :

• 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.

1. Simulink Model of the Washing Machine :

Control Logic And Flow chart :

Explaination :

• For implimenting the control logic of the washing machine , i have created States as Power for power supply , Water supply as Water , Followed by Soaking , Washing , Rinsing and Dry Run States .
• Here i have applied one condition using Junction Point that the If the Power supply is on means 1 then and then only process will be proceed further to water supply .

• Initially there was an error thrown in the Dignostics View , which can be seen below as ,

• Here i made direction of the Transition from power to Junction in the wrong direction which is coorected by Correcting the direction .
• After the water supply process is done , there will be Saoaking process For 200 seconds ,which will automatically will go to the next process .
• Then there will be Washing process fro 100 seconds followed by the Rinsing process for 20 seconds .
• and then finally Dry Run proceess will run for 50 seconds and then machine will stop .
• Then we have create the input and output through the left side symbol panel , where we have to define the input and the out put parametrs .

• For each process i have connected a lamp which will indicate processes .
• For making power supply on and off i have provided an slider Switch .

Results :

when Power and Water Supply is Off :

Both Power and water supply is on :

Soaking Process :

Washing Process :

Ringsing Process :

Dry Run Process :

Peocess End :

2. Implimenting the control logic for the Gear Box :

Simulink Model :

Logic Control and Flow Chart :

Explaination :

• For implimenting the Control logic for the Gear Box , we have to creat an various States as Gear 1 , Gear 2 , Gear 3 , Gear 4 and Gear 5 .
• For each Gear to Shift from one to other gear , i have made the Transition condition that 1st Gear will be activated when speed will go above the 0 and other conditions are also defined in the same way can be seen in above control logic model .
• I have provided reverse situation also , so that we can increase and decrease the speed as well .
• Displays are added to indicate which gear is activated , here 1 means the respective gear is active and 0 means deactiveted .
• each Gear is connected with Lamp which will activeted whenever gear will be shifted .
• Then Input and outputs are defined in symbol pannel as ,

Results :

• The Simulink Model is attached below .
• When 1st speed goes above 0 :

• Speed Greater than 15 :

Speed Greater than 25 :

Speed Greater than 40 :

Speed Greater than 60 :
