Week - 4
Task:1
Aim: To IMplement control logic of a washing machine using stateflow in simulink
Objective: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
Model:
model of washing machine in simulink
Note:
parameter consider while create thee model
value '1' mean there is inputs and '0' means is no inputs
when lamp shows green the task in process and when shows red the task ends
Chart diagram:
Inputs parameter and output parameter
we have given the inputs as water ,soak,washing ,rinsing,dryer,cycle as outputs of the chart and we have consider water_supply and power_supply as inputs values
Results:
There are two condition asked in create model
Condition:1 is create model when the water supply is off
From above model we conclude that ,we can see that clearly indicate of lamp is showing Red color hence there no supply
Condition:2 is created model when water supply is on
Now we providing the water supply in this case
From above model we conclude that ,we can see that clearly indicate of lamp is showing green color hence there is supply water and indicates the process complection.
conclusion
The simulation of the washing machine using state flow is done and results are satisfactory

Task:2
Aim:To make the simulink chart for the Gear shift logic
Objective :
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
Block diagram of model
Condition:
Speed Range(kmph) Gear color
0 to 15 1 green
16 to 25 2 yellow
26 to 40 3 purple
41 to 60 4 blue
Above 61 5 red
Chart diagram:
Inputs parameter and output parameter
Note : we given speed as speed an input and we gear as output
simulation times as 'inf' simulation should run until we stop
Inputs : we use slider gain provided input to chart
Results :
The outputs produced is recoreded in diiferent speed range
Gear :1
speed range 0 to 15 kmph
input speed given is 12 kmph
color :green
Gear :2
speed range 16 to 25kmph
input speed given is 22 kmph
color : yellow
Gear :3
speed range 26 to 40kmph
input speed given is 35 kmph
color : purple
Gear :4
speed range 41 to 60kmph
input speed given is 50 kmph
color :blue
Gear :5
speed range 60 and above kmph
input speed given is 80 kmph
color : red
conclusion
The simulation of the Gear shift using state flow is done and results are satisfactory
