Week - 4
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
Answer:
Control logic of a washing machine using Stateflow as shown below inside the chart block:
- 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 the next 20s & dryer runs for 50s.
If the Power & water supply is on, all the Washing processes will happen. Greenlight in LED will indicate that the process is done.
If the Power & water supply is off, all the Washing processes will not happen and the washing process will be terminated. Redlight in LED will indicate that the process is not done.
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: Simulink Chart for the Gear shit logic is shown below:
Here Speed is the input parameter & Gear is the output parameter. The gear will shift accordingly based on the speed range.
Speed Range(kmph) Gear
0 to 15 1
16 to 25 2
26 to 40 3
41 to 60 4
Above 61 5
The result is shown below:
Here the Speed is greater than 60Kmph, therefore the gear is in 5th position.
