AIM: Make a Simulink chart for the "Gear shift" logic as per given conditions and give speed input while the simulation is running & display the gear number.
LOGIC DIAGRAM
1. To create a Simulink model of gear shift create a Stateflow chart and start with the power block which is connected to the breakpoint and a junction with power==0 condition and connected to speed block(state) power==1 so that when the speed is above 1 the process will start flowing to gears.
2. Here I have mentioned speed to Convey our conditions as above speed greater than zero the gear shift should start the cycle of changing to next gear.
In gear one, the breaking point is mentioned up to 16 then it is respectively changing till speed 61.
4. From gear five till gear one there up arrow(breaking point) the speed is decreased to zero so that we can shift our gear not only increasing it can be decreased too.
5. After completion of our chart, we can see the inputs power speed and outputs gear
6 I have connected the two constants to power and speed so that when the switch is on the power will be
Washing-
During the wash cycle, a large plastic agitator (green) turns around, moving your clothes through the water. When the wash is finished, the pump drains the water from the outer drum.
RINSING:
The dirty, soapy water is drained, then the washing machine is refilled and your clothes are "rewashed in clean water. Spin: All the water is drained completely, then your clothes are spun very fast and excess water is removed thanks to centrifugal force.
DRYER:
They work by pushing warm dry air through your wet washing to extract moisture, then cooling the now humid air in a heat exchanger to condense the and the cycle repeats.
1) STATE-FLOW:
Systematic solution of a problem is possible with sequential, unambiguous and realizable finite process step set. This set is called "algorithm" and it is one of the most important part of the programming languages. In this study, it is represented how to learn algorithm by using Simulink Stateflow. In flow diagram-based algorithm learning.
AIM:
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
Sooking 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
2. Make 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
Above 61
4
15
Give speed input while the simulation is running & display the gear number
PROCEDURE:
WORKING PRINCIPLE OF A WASHING MACHINE:
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 pipes hence utilizing centrifugation to both clean and partially dry the clothes loaded in it. Thus the processes are electrically controlled, such as the drum, valves, pump, motor and heating. The valve opens again and the dirty water drains out of the drums. The pump works to help get rid of the water. The valve lets clean water in again into the drums. The four process are:
SOAKING:
It is used to dip clothes in detergent water to remove dirt from the clothes. In this function customer need to select soak from a panel. Soak-This function is available with wash timer, In 42 min of washing 27 min is soak and 15 min machine will wash the clothes.
