Week -2
1)
- Make a Simulink model of Doorbell using solenoid block with the following details:Principle-The solinoied valve is an electromagnetic with wire winding & piston inside it.when electric current is passed through the wire than electromagnetic filed praduce which puse is towadrd metal piston.due to that metal piston hits the tone bar so sound praduced.
Theory-
solenoied valve is connected to ideal traslational motionsensor and mechanical traslational referance.in the case solenoied valve is consist of iron core mounted on non magnetic metal bar.when power off than piston is downword side.when the power is turn on at that time electromagnetic field produce than the piston move towadr right hand than srtiks the tone bar and produce the sound.
Simulink blocks used-ps -simulink,simulink ps,scope,solenoied valve,pulse gennerator,electrical & mechanical referance,battery,switch,ideal traslator motion sensor,display,solver confuguration,
Output:
The input signal of pules generator:
2
Use a thermistor to sense the temperature of a heater & turn on or turn off the fan
Input signal-
Temperature source: 20 °C from 0 to 10 seconds, 27 °C from 10 to 30 seconds, 23 °C from 30 to 50 seconds
