Week -2

Q1.

*The pulse generator is used to create square wave pulse 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 externalsignal is greater than the thresold parameter then the switch is closed,otherwise switch is open.
*The positive terminal of the switch is connected and the negative terminal is
connected to the electrical reference.
*The solenoid block is connected with 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 solenid block R 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 solver settings information for simulation.

Pulse generator block parameters are mentioned below.

As given in the question the switch is closed for 2 seconds and then released. So the phase delay is given as 2 seconds.

Pulse generator output.

Output.

Q2.

Signal builder block is used to input the values as per given conditions:
At point 1, time=0 seconds, temperature = 293k
At point 2, time=10 seconds, temperature = 293k
At point 3, time=10 seconds, temperature = 300k
At point 4, time=30 seconds, temperature = 300k
At point 5, time=30 seconds, temperature = 296k
At point 6, time=50 seconds, temperature = 296k

*Controlled temperature source represents an ideal source of thermal energy,can maintain a controlled temperature difference regardless of heat flow rate.The temperature difference is set by the physical signal part S. A positive temperature difference causes the temperature at port B to be greater than the temperature at port A.
*Thermistor is a type resistor whose resistance is based upon temperature.
*A linear resistor is used in order to control amount of current from the battery.
*The voltage sensor is used to convert the voltage measured between two points into a physical signal.
*Voltage source reference block is given.
* Solver configuration: Each physical network represented by a connected simscape blocks requires solver setting information for simulation.
