Simulink model of Doorbell using solenoid

The working of Simulink model of Doorbell using solenoid block has been implemented here.

each block carries specific functions respectively.

1. the wave generator is used to produce the wave with duty cycle of 50% and of period 4 seconds.

2. switch block is used in such way that it close itslef only after getting value greater than its threshold value.

3. ps to simulink or simulink to ps converter block is use to convert the physical value to simulink value or vice versa.

4. solenoid block connected with battery having electrical reference is use to complete the circuit.

5. ideal force sensor block is use to sense the force produced by solenoid with having solver configuration.

6. the result is then presented on scope.

The ss of scope result is posted below.

Thermistor Model

this model represents the working of thermistor.

1. the signal bulider block is use to generate the temperature signal with respect to time.

2. simulink to ps converter is use to produce the suitable signal for controlled temperature source block with having solver configuration which is further connected to thermistor.

3. then for sensing the thermistor behaviour current sensor is connected in series with it to sense the change in current with respect to temperature signal.

4. switch is connected to current sensor with having some threshold value of it to work properly with ON/OFF conditions.
