Week -2

For doorbell model using solenoid we need different block diagram.

1.Solenoid block - It represent electrical characteristic and generats force.

2.Ideal translation motion - to observe the physical movement of the plunger.

3. Mechanical translation reference - It represent a reference point of mechanical rotational ports.

4. Solver configuration - For simulation every physical network requires a solver configuration.

5. PS-Simulink convertor - It convert physical signal to simulink.

6. Simulink-PS convertor - It convert simulink to physical signal.

7. Scope - It represent a simulink graph.

8. Switch - It is for controlling external graph signal.

9. Battery - It is to provide power supply to a solenoid where positive terminal is connected with switch and negetive terminal is connected with electrical reference.

10. Pulse generator - It generates square pulse at regular interval.

Electrical reference block - It represent an electrical ground.

for this simulink model we need solenoid,switch,battery. A solenoid is connected with the battery and in between switch is connected. WIth the switch physical signal is connected for ON/OFF operation.For operation of switch we need a pulse generator which generate contineous square pulse.Now it forms a close loop with a connection of electrical reference in negetive terminal.In the solenoid block there is two variable i.e R & C which represent plunger and fixed point. Solenoid R is connected with the  R of Ideal translation motion sensor which sense motion of the plunger. In ideal translation motion sensor there is V & P which denotes velocity and position ,in this we need the change in position of the plunger so we need only P as an output. C of a Ideal translation motion sensor is connected with the mechanical translation reference.After this we need to connected the output P of the Ideal translational motion to the PS-simulink which convert physical signal to simulink and then is connected with scope block which generate a graph
