1)Speed control of a DC motor using BJT H-bridge.Objective:A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’.B. Comment on the armature current shoot-up from the scope results.C. Refer to the help section of ‘The Four-Quadrant Chopper DC Drive (DC7) block’. Compare…

Objective: To carry out the following studies:1. Which types of power converter circuits are employed in electric and hybrid electric vehicle?2. An Electric Vehicle's powertrain with 72V battery pack in shown in the diagram below. The duty ratio for acceleration operation is 'd1'and for the braking operation the duty ratio…

1. What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type? Mapped and Dynamic subsystem of Electric Motor/Generator   Mapped Model:The mapped model is one type where the data points are pre_assigned in lookup tables.The engine or motor torque required…

Aim: To use the ADVISOR tool for simulation.Objective:1. Using EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, To find whether the vehicle can travel for 45 kmwith FTP drive cycle? and To Conclude observations.2. In the above case, try changing the battery capacity and repeat the simulation.3.…

Project 1 - Controlling a DC motor using PWM and monitoring its Running status AIM: to control a DC motor using PWM modulation an dto moniter its running status by writing a aurdino code. code :- void setup(){ pinMode(3, OUTPUT); // sets the pin3 as output pinMode(0, INPUT);// sets the pin0 as output pinMode(1, INPUT);//…

AIM: To study the system level simulation of an all terrain vehicle. keywords: CVT, lookup table, Dashboard, baja ATVSOFTWARE: Matlab, SimulinkOBJECTIVE:1. Study the baja ATV model without dashboard.2. Study the baja ATV model with dashboard.3. Study the baja ATV model using lookup table without dashboard.4. Study…

Project 2 - Implement the Code for controlling the retraction and extension of Airplane’s landing gear AIM: to control the retraction an extraction of airplanes landng gear can be implemented using finite state machine(FSM). FSM is the most efficient algorithym which is mathamatical model computation. #include<.stdio.h>…

An Interface is a collection of loosely bound items that have a common functionality or attributes. Interfaces contain method signatures, properties, events etc. Interfaces are used so that one class or struct can implement multiple behaviors. C# doesn’t support the concept of Multiple Inheritance because of the ambiguity…

AIM:  1. implement control logic of a "washing machine" using state flow as per given sequence  if the power supply is available the system gets activated if the water supply is not available, stop the process and indicated through LED soaking time should be 200s followed by washing machine  time is 100s…

1 AIM:  to make a Simulink model of a doorbell using solenoid block SIMULINK MODEL EXPLANATION: the pulse generator is used to create a square wave pulse at regular intervals. the blocks waveform parameters. amplitude, pulse width, period, and phase delay. determine the shape of the output waveform the switch block…
