Week - 4

Ans1.

THEORY:

• Implementing control logic of a “washing machine” using Stateflow.
• Condition 1: If the power supply is available, the system gets activated
• Condition 2: If the Water supply is not available, stop the process & indicate through LED
• Condition 3: Soaking time should be 200s followed by Washing time of 100s.
• Condition 4: Then rinsing happens for next 20s & dryer runs for 50s

BLOCK USED:

• Chart: A finite state machine is a representation of an event-driven (reactive) system. In an event-driven system, the system responds to an event by making a transition from one state (mode) to another. This transition occurs if the condition defining the change is true.
• Constant: Generates a real or complex constant value signal.
• Display: Display input values.
• Lamp: Display a color that reflects an input value.

MODEL OPERATION:

• Basic constant block used to indicate power supply and water supply.
• Above signals connected to chart.
• Each output were connected to display and lamp accordingly.
• Inside Chart the stateflow was made by applying the conditions given.

Ans2.

THEORY:

• Making a Simulink chart for the “Gear shift” logic.
• condition1: 0 to 15 Speed Range(kmph) 1(Gear)
• condition2: 16 to 25 2
• condition3: 26 to 40 3
• condition4: 41 to 60 4
• condition5: Above 61 5
• Give speed input while the simulation is running & display the gear number.

BLOCK USED: Each block has been explained in previous question.

• Constant
• Display
• Scope
  
• Chart

MODEL OPERATION:

• One constant block is connected to chart to varring the input speed.
• Output of the chart is connected to Display to observe the gear change.
