Week -2

1. DOORBELL

Pulse generator is use to great square wave pulse at regular interval 2 sec with amplitude 1 and pulse width 5% of period
To understand the pulse signal add the simulink to ps converter then output of simulink to ps converter connect the switch inpute
2nd end connected to positive terminal of battery and 3rd end connected to positive terminal of solenoid
for complete operation solver configuration and electrical referance are add
for 2nd loop solenoid and ideal translation motion sensor are connected in series with mechanical translation referance
3rd end of ideal translation motion sensor are connected to ps-simulink converter then this converter connected to scope
scope having 2 port 1end connected to end of ps-simulink converter and another connected to simulink-ps converter

Observation

after every 2 sec squre pulse generate

2. Thermister

Here signal builder is use to produce signals in the form of temperature in kelvin
Then its convert into physical signal so use simulink-ps converter end of converter output conected to control temp source
controll temp. source one end connectedto thermal referance and another end connected to thermister in between use solver configuration
resister connected to series of thermister and voltage sensor connected to paraller of resister
resister end and voltage sensor end connected to battery with electrical referance
output of voltage source V converted to simulink so use ps-simulink converter with one exctra connection paraller
one paraller connection is connected to scope and another connection connected to switch
switch havving three input 1st is constant which is 1 , 2nd is treshold which is >0.0115, 3rd is constant which is zero
then connection connected to scope and display

Observetion

from 0 to 10 sec fan is off because temp. is less than 25 degree C

from 10 to 30 sec fan is on because temp. is more than 25 `degree`C

from 30 to 50 sec fan is off because temp. is less than 25 degree c
