Week -2

Solenoid bell

Plot 1:-

Plot 2:-

Explanation:-

1. to create a circuit and give theinput values here pluse generator is given as input block

2. simulink to ps convertor connect pulse generator and switch block,one end is connected with battery and other end connected with solenoid

3. in that pulse generator input values as amplitude as 1 period of sec 4 pulsewidth as 50 phasedelay as 2 sec

4. the solenoid block represents the electrical characteristic and generate force for solenoid, its convert electrical to mechanical

5. plunger is connected to ideal transaction motion sensor

6. a solenoid is connected to ideal transaction motion sensor by the reference of mechanical translation

7. the output is connected from ideal transation motion sensor with scope by using ps converter

8. and the graph will appear in scope block

Thermistor

Signal Builder :-

Plot :-

Explanation:-

1. The Signal Builder block allows you to create interchangeable groups of piecewise linear signal sources and use them in a model. In the Signal Builder window, create signals and define the output waveforms.

2. the blocks contain signalbuilder,control temperature source, resistor,voltage sensor,battery,thermistor,electrical reference, thermal reference,solver configuration,switch,ps to simulink convertor,simulink to ps convertor,two conatant values and scope

3. we create a input that question asked in challenges page

4. first we need the condition as 25deg celcious as off condition of fan

5. by using conastant block input value as 293k to the control temperature source

6. the control temperature works whatever as input value it generates the corresponding output voltage source.

7. so we get that output voltage value through display block and that is given constant thershold for switch block to off the fan,when that value is incerese the fan shoud be on.

8. then we connect signal builder block with different inputs as given in the question,the scope shows the result of fan running condition.
