Week - 4

objective 1:- 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

After all the processes have completed turn on the finished LED.

flow chart:-

symbol pane:-

in this elec.& water are input data. finish,stop,wash,activation, drying, rinising, soaking are output data.

block use:- constant, chart, display, lamp

result-1:-

result-2:-

explaination:-

result-1 shows that when power & water is available then washing process will start.

result-2 shows when power & water any one them is not available then washing will not start.

in washing process water soaking is for 200sec, washing is for 100sec, rinsing 20sec & finally drying 50 sec, the lamps are use as indicators when it glows the respective activity is on.

objective-2:-

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

Give speed input while the simulation is running & display the gear number.

state flow model:-

blocks used are constant, slider gain, chart, display.

flow chart:-

here g is use as common parameter in all state, which is connected to display of model.

condition is when speed is <=15 gear will be 1, <=25 gear will be 2, <=40 gear 4, <=60 gear 5.

if speed >15 gear 2, >25 gear 3, >40 gear 4, >60 gear 5 will be shown in display.

result:-

explaination:- slider gain is use for giving input speed, to change the input speed while simulation the run time should be kept infinite(1/0). as we change the input speed from slider gain the following gear is shown in display.
