Week -2

AIM: to make a simulink model of dorebell using solenoid block

EXPLANTION OF BLOCK DIAGRAM USED IN MODEL :

1)PULSE GENERATOR : to provide the input to the model

2)BATTERY : is used to give current source to the ckt

3)SIMULINK PS CONVERTER AND PS TO SIMULINK CONVERTER: is used to convert th simulink model to physical state and vice versa in ps to simulink model

4)SOLVER CONFIGRATION : is used to solve the model

5)SOLENOID: is used to convert the electrical signal into a mechanical output

6)IDEAL TRANSLATIONAL MOTION SENSOR : is used to sense the plunger movement and gives the output

7)ELECTRICAL AND MECHANICAL REFERENCE : is used as a reference in the model

8)SCOPE : are used to show the output wave

RESULT : in the output plot we can see in every 2sec there is vibration in plot which shows plunger hit the bell

AIM: use thermistor to sense the temperature of heater and turn on and off the fan as per given condition

EXPLANATION OF BLOCK DIAGRAM USED IN MODEL :

1)SIGNAL BUILDER :to provide the given condition of the heater at which thermistor sense the tem (from 0 to 10 sec tem is 293k,from 10 to 30 sec tem is 300k,from 30 to 50sec tem is 296k)

2)CONTROLLED TEMPERATURE SOURCE :are used to take input from signal builder and translate to thermistor

3)BATTERY : are used to provide the current to the ckt

4)THERMISTOR :are used to sense the temperature and gives the output

5)RESISTOR AND VOLTAGE SENSOR :are used to pass the temerature output values to the switch and volatage sensor are used to sense the voltage accross it

6)SWITCH: are used to when the threshold value is greater than or equal to constant then it on the fan

7)CONSTANT :two constant are used if threshold value is greater than 300k then give value 1 or it will give 0 value if condition not satisfy

8)SCOP: are used to show the output graph

RESULT: from the plot we can say that fan get on at 25 degree celcius or above and all the temperature value fan is off
