Week - 4

A washing machine by spinning at 800-1600 rpm helps soap and dirt with it to leave the surface of the cloth via centrifugal force and into outlet pies hence utilizing centrifugation to both clean and partially dry the clothes loaded in it. thus the process are electrically controlled, such as the drum valves pump motor and heating.the valve opens again and the direct water deains out of the drums.the pump works to help get rid of the water the valve lets clean water in again in to the drums.

there are four processes

1 soaking

2 washing

3 rinsing

4 dryer

CONTROL LOGIC OF A WASING MACHINE

If checks for the extent of dirt and grease, the amount of soap and water to add direction of spin and so on.

The machine rebalances washing load to ensure correct spinning. else it reduces spinning speed if an imbalance is detected. even distribution of washing load reduces spinning noise.

if the two inputs are given for the power and water supply once the inputs are given outputs are displayed by the flow chart as per the given sequence. the system are observed for sometime then it is checked and the process is completed by green light as displayed

Question no 2

A gear shift mechanism for a manual transmission includes a shaft axially movable for selecting shift planes and rotatable for engaging the gears defining the shift planes. the shaft is healed in a reference shift planes by two helical springs.

Results

Thus the control logic of a washing machine using satateflow is processed as per the given sequence and LED lights are turns to the green colour and the system is completed

A simulink model os created for the gear shift logic and using slider gain the values are obtained
