Week - 4

Aim: Implementation of control logic of Washing Machine.

Objective: Implementation of the control logic using the following 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 50.

The Simulink model is shown below:

The control logic diagram is:

The simulink diagram when one of the inputs are zero is:

The simulink diagram when both the inputs are zero is given as:

Aim: Implementation of a "Gear shift" logic

Objective: Display the gear number according to the following conditions:

Speed Range(kmph) Gear

0 to 15 1

16 to 25 2

26 to 40 3

41 to 60 4

Above 61 5

The chart for the control logic is shown below:

The different cases are:

case 1: If the Key=0, then the lamp would indicate red colour and the gear shifting would not start

case 2: If the Key=1, then the lamp would indicate green colour and the gear shifting would start

case 3: By varying the speed in the speedometer using slider gain mechanism, we get the gear position according to the given conditions.

we get the following gear as output,

As we have given the speed as 50km/hr, gear 4 would be activated from the given conditions.
