Week -2

>>Program 1

>> Simulink editor window

>>Scope result

>> Explanation:-

In this Program, we have Simulink for bell operation.

- The switch is been operated according to the program in Pulse Generator.

- To create a situation where the switch is closed for 2 seconds and then released, the parameter in the pulse Generator is changed like-

- Solenoid is a device that takes electrical signals as input and converts them into mechanical force by moving the plunger.

-Ideal Translational Motion Sensor block measures velocity or displacement in a mechanical translational network.

- In solenoid port R moves towards C, So for ITMS R is the input port and C is the common port.

- Here we have measured the position of the plunger for that scope is connected to the P port of ITMS through a PS-Simulink converter.

>>Program 2

>> Thermistor Model

>> Temperature Signal Builder

>>Scope of Voltage Sensor

>>Scope of Switch to turn on the fan at a given condition

>>Explanation

-In this thermistor modeling, the three different temperature range is given out of which we have to turn the fan at >25celcius.

- Signal is generated using 'Signal Builder', where the time range is 50sec (x-axis) & Temp on (y-axis) for three different ranges as shown in the figure.

- Controlled Temperature Source:- It has an 'S' port for input signal, an 'A' port for Thermal Reference & a 'B' port for input temperature to Thermistor.

- Thermistor:- Device used to give the value of Temperature in terms of changing Resistance across circuits.

- Voltage Sensor is connected in parallel to the resistor.

- Reference is used for..............

- Solver Configuration is used for ...........

- In switch 2 condition is provided to turn on or off the fan, if the middle port value is above threshold '0.01196' then condtion1 is true else condition 2.

-To find the threshold value voltage is measured at 25Celcius.

- In the scope, you can find the graph for time vs fan condition.

-Stop timing is 50sec.
