fig :simulink structure of washing machine

Fig: Control Logic of Washing Machine

from above 2 figure we can clearly see that we need to input power and water, and if power condition is false it remain in same state and and power become high it state shit to next state water, here also it checks for water if water high is continue to next state or it remain in sam state and RED LED is lit, next state is soaking in this state i used delay condition so that after 200 sec only it shift to next state, wahsing also uses dealy 0f 100 sec and after 100 sec rinsing , rinsing is done for 20 sec post this Drying is done for 50 sec and once it complets it lit Green LED

fig: input of gears state

i have given a step input value 3 and slider gain of 25 to memic real contion of speed

fig: control logic state of gear shifter

In the above fig we can see one how the cart will behave if speed is below 15 1st gear is engaged and speed more than 15 and less than 25 2nd gear is enaged and if speed is more than 25 and less than 40 3rd gear and more than 40 and less that 60 4 th gear is engaged and above 60 5th gear is enaged.

fig :output of gear slider gain graph= speed and char graph = Gears
