1) Doorbell using Solenoid block with simulink model situation where the switch is closed for 2 seconds and then released.
Input as a pulse generator period is 4 secs,pulse width 50% of period and phase delay is 2secs connected with solenoid is connected in switch (switch and pulse generator not directly connected use simulink ps converter) also connected in battery positive terminal is connected in switch side neagative terminal is connected in solenoid side,this part side also connected in electrical reference, and solver configuration is connected this side electrical side
mechanical side R and C, R and C is connected in Ideal Translational Motion Sensor this is directly not connected in scope with using PS-Simulink Converter also connected in mechanical Translational reference.
Operation :-
Input as first 2sec is off condition and another 2 secs on condition for two time continously ring the bell.
OutPut:-
2)Thermistor to sense the temperature of a heater & turn on or turn off the fan
Conditions:-
Temperature source: 20 °C from 0 to 10 seconds, 27 °C from 10 to 30 seconds, 23 °C from 30 to 50 seconds
Fan conditions: ON if the temperature above 25 °C, OFF otherwise
Input as a using repeating sequence stair this is used for kelvin so Degree is converted to kelvin and Controlled temperature source (Its not Directly connected used for Simulink PS Converter its set the Input Handling is Filter Input,derivatives calculated) is connected in sensing the temperature its also connected in thermal reference. Thermistor is operate on a heater condition its also connected in battery,resistor,solver configiguration and also connected in voltage sensor its sensing the voltage its also connected in switch (switch is connected using PS-Simulink Converter)its one ON (1)Condition and another OFF (0) condition.set the thershold value Purpose the set the value its reached value thermistor on condition connected with scope.
OutPut:-
first 0 to 10 secs thermistor is off condition its 293kelvin and 10 to 30 secs
and above the temperature 293 thermisor on condition ,298kelvin reached on the fan reduce the temperature off the fan
