Week -2

Challenge Report :-

Blocks used :

i) Pulse Generator - This generator produces block wave pulses, The parameters are Amplitude, Period, Pulse width, Phase delay.

ii) Simulink - PS Convertor - This convertor converts simulink input signal to physical signal.

iii) Switch - This switch opens and closes the circuit.

iv) Battery - It provides voltage to the system.

v) Solenoid - The main use of this solenoid is to convert the electrical input into an mechanical output. This results in the induction of E.M.F .

vi) Mechanical and Electrical reference - This reference provides reference points to the respectivr goals.

vii) Ideal transitional motion sensor - This device converts the the variable measured between two mechanical translational nodes into an control signal .

viii) Scope - It is used to view the characteristics of the property with respect to time.

Result :

For every two second the switch is turned off and on so that such scope result is obtained.

b) Thermistor to sense the temperature of a heater & turn on or turn off the fan :

i) Signal Builder - In the signal builder give the signal values as per the inputs given.

ii) Controlled temperature source - It represents an ideal source of thermal energy thet is powerful enough to maintain specified temperature difference accross the source regardless controlled by the system.

iii) Thermistor - It is a device which is used to sence the temperature of a given source .

iv) Resiator - It is adevice which is used to resist the current flow. In here it is in the relation of V=I.R.

V) Voltage Sensor - It is an ideal voltage sensor, this device converts voltage measured between two pts. of an electrical circuit into physical signal.

vi) Voltage Source - This block represents the voltage source with D.C and A.C.

vii) Electrical Reference - It represents an electrical ground.

RESULT :

Give the signal values in the input builder.

Connect the thrmistor , voltage source , voltage sensor, and the resistor.

Connect the thermal reference and an electricel reference in the respective places.

Select the switch block and connect two constants with the switch block.

Then connect a scope at the end , now run the simulink model.
