Week -2

AIM:

To make a simulink model of a doorbell using solenoid block

To use a thermistor to temperature of a heater & turn on or turn off the fan.

1.Door Bell

simulink model explanation;

. The pulse generator is used to create square wave pulses at regular intervals. The block waveform parameters Amplitude pulse width,period and phase delay ,determine the shape of the output waveform.

. The switch block used is controlled by external physical signal .if the external signalis greater than the thresold parameter then the switch is closed,otherwise switch is open.

. The positive terminal of the switch is connected to switch and battery and we will get a complete electrical circuit.The port c is connected with mechanical reference.

. The ideal translational sensor is connected with soleniod block R to observe the movement of the plunger.

. scope is connected with the ideal translational sensor to get the output.

. PS-Simulink converter is used to convert the physical signal to simulink signal.

. Solver Configuration Each physical network represented by a connected simscape blocks requires sover setting information for simulation.
