Week -2

1) Make a Simulink model of Doorbell using solenoid block:-

Ps-simulink and simulink-ps converter :-

The block set are basically used to physical system to simulink signal are voice versa

Pulse generater:-

The analog input is amplitude and frequency in with input transmitted

electrical and mechanical reference:-

In that reference is move through the ground source as a base

scope:-

scope is nothing but to plot of the output

battery:-

The battery s used as to positive and negative terminal of electric power comes through the electric flow

solinoid:-

The solinoid is nothing but the electromagnatic device at represent of the block

Ideal translated motion sensor:-

. In this type of sensor is to input tha position or velocity and the system to generate the output

The switch:-

The switch is used to control to flow the system manually or automatically at using this type of switch

Solver configuration:-

This typ of blocks are generate the equation f(x) = 0 where we find the x value and generate the output with represent of this block

2) the temperature of a heater & turn on or turn off the fan as per the below conditions:-

Thermistor: thermal resistor is defined as a type of resistor whose electrical resistance varies with changes in temperature. Although all resistor's resistance will fluctuate slightly with temperature, a thermistor is particularly sensitive to temperature changes.

We bulid the singnal of heater and turn on and turn off the fan as per the below conditions

And we creat simulink block of the temperature of the heater :-

The signal is connect through ps to simulink converter and another link to connect at scope

Let well ps to simulink converter was. connecting to ideal temperature source and the ground fource was thermal reference and solver configuration

Let we move on the another block it tranmister to resister to connect at voltage sensor and total resister and thermister and voltage sensor to connect at the battery and move on ground fource at electrical refference

And the voltage sensor at another link was connect at the switch and sub joint was constant 1 and constant 2

finally the switch was connecting as tha display and scope 1 we can run and get the output can be display
