Control logic of washing machine and gear shifter using Stateflow

Implement control logic of a “washing machine” using Stateflow as per the given sequence.

If the power supply is available, the system gets activated.
If the water supply is not available, stop the process and indicate through LED.
Soaking time should be 200s, followed by washing time of 100s.
Then rinsing happens for next 20s and dryer runs for 50s.
After all the process have completed, turn on the finished LED.

Explanation:

The state of washing machine is defined (ON/OFF), and the required conditions are applied.
Then, the further washing states are defined with the required conditions.
Here, the variables are defined as inputs (Washing machine ON/OFF) and outputs (Soaking, Washing, Rinsing, Drying).
The stateflow chart is connected to two constant blocks which is then connected to two slider switches which control the power supply and the water supply.
The outputs are connected a display block each which is then connected to a lamp to indicate the process.

Make a Simulink chart for the “Gear Shift” logic as per the below conditions.

Explanation

First, each individual states in stateflow chart is defined as per the speed and gear requirement. The conditions are applied for which the gear changes with respect to speed.
The properties are defined for each variable in the symbols pane (speed=input) (g1, g2, g3, g4, g5=output).
A slider block is connected to a constant block which is connected to the stateflow chart.
A number of display blocks are connected to each output (g1, g2, g3, g4, g5). This display block is connected to a light source indicates the gear position.
