Challenge

Week - 4

AIM:

To implement control logic of a "washing machine" using stateflow as per given sequence

OBJECTIVE:

After all the process completed we have to turn ON the finished LED

STATEFLOW:

State flow starts with the power supply state and the logic is that if power input is 1
If the power supply is 0 (where no power supply)and a lamp can be used to indicate
State flow chart of washing machine is used as inputs to be provided for the washing machine.
The following process of washing machine are giving power more then water comes in where soaking starts with a given period of time 200secs.
The washing in period of 100secs follows rinsing and drying of 20s and 50s before machine stops running.
The fibnal state consist of a value of 1 at the entry and it allows for indicating the cycle completion lamp.

where in the above simulation power supply is given ON
So the LED indicates the green colour
The water supply is not given so the LED so it is indicated in red which shows the error supplying of water.

This is the initial simiulation of washing machine before giving power and water supply

Where the above simulation shows the working of model
Where the power water is ON so the soaking process starts with the time period of 200secs which the soak LED indicated of soak process undergoes.

The above simulation shows the completion of process involved in washing machine with the LED indication

GEAR SHIFT:

AIM:

To make a similink chart for the GEAR SHIFT logic as per the conditions.

OBJECTIVE:

Speed range (kmph) GEAR

0-15 1

16-25 2

26-40 3

41-60 4

Above 61 5

Give the speed input chart while the simulation is running and display the gear number

FLOW CHART:

State flow chart is used as the inputs to be provided for the gear shift simulation. where the command work on the speed range given for each block.

Simscape model for gear shift .
The blocks used are slider gain, chart, display, scope and gear.
The slider gain is used to acclerating or deacclerating the vehicle with given values for a limit of low to high.

where accleration is given as 26.4 in slider gain the output shows the 3 which is the vehicle running in 3rd gear at a accleration of 26.4.

where the accleration is given as 52.8 in slider gain the output shows 4 whih the vehicle is running in 4th gear at a accleration of 52.8.

GRAPH:

The top plot shows the gear position indicator and the bottom plot denotes the speed input with respective time.

RESULT:

The control logic for washing machine and simulink chart for gear shif is moulded.
