TASK-I:
AIM:
'To implement control logic of a washing machine using Stateflow in Simulink'.
OBJECTIVE:
1. To implement the control logic of a washing machine using stateflow as per given sequence:
a) If the power supply is available, the system gets activated.
b) If the Water supply is not available, stop the process & indicate through LED.
c) Soaking time should be 200s followed by Washing time of 100s.
d) Then rinsing happens for next 20s & dryer runs for 50s.
After all the processes have completed turn on the finished LED.
MODEL:
pictorial Representation of Block Diagram:
Parameters:
1) Value '1 means there is input.
2) value 'O ' ' means there is no input.
Conditions:
I) When Lamp shows Green, The task is In Progress.
2) When Lamp shows Red, The task Ends.
CHART DIAGRAM:
PARAMETERS:
We have given water, soak, washing, rinsing, dryer, cycle as Outputs of the chart.
We have given our water_supply & power_supply as Inputs of the chart.
OUTPUT:
CONDITION 1: When the water supply is turned off.
Condition 2: When water supply is turned on
CONCLUSION:
• The simulation of the Washing machine using State flow is done and the result is satisfactory.

TASK-2:
AIM:
•To make a Simulink chart for the "Gear shift" logic'.
OBJECTIVE: Making a simulink chart for the Gear Shift for the below mentioned paramters:
Speed Range(kmph) Gear
Oto 15 1
16 to 25 2
26 to 40 3
41 to 60 4
Above 61 5
MODEL:
block diagram of model:
CHART DIAGRAM:
PARAMETERS:
Here we give Speed as an Input for the chart.
Here we give GEAR as an Output for the chart.
Simulation Time parameters: Here we gave time as ' Inf ' for our simulation should run until we stop it.
INPUT:
We use slider gain to provide input to the chart.
OUTPUT:
The Output produced is recorded when it's displaying the each gear.
Gear-I:
Speed range: O to 15kmph.
Input speed: 10kmph..
Color: Green.
Gear-2:
Speed range: 16 to 25kmph.
Input speed: 20kmph.
Color: Green.
Gear-3:
Speed range: 26 to 40kmph.
Input speed: 30kmph.
Color: Green.
Gear-4:
Speed range: 41 to 60kmph.
Input speed: 50kmph.
Color: Green.
Gear-5:
Speed range: above 60Kmph.
Input speed: 70kmph.
Color: Green.
CONCLUSION:
Created a State Flow for Gear Shift using Simulink and the results are satisfactory.
