  Q. Create a MATLAB model of electric car which uses a battery and a DC motor. Choose suitable blocks from Powertrain block set. Prepare a report about your model including following: Objectives:  1. System level configurations 2. Model parameters 3. Results 4. Conclusion   Solution: Electric Vehicle:…

Part A: 1. Search and list out the total weight of various types of aircrafts. The weight of the aircraft is needed to be calculated by the pilot for every flight to ensure the aircraft remains within the weight limitations set by the manufacturer. These limitations are to ensure the aircraft is able to perform and recover…

Q.1: For a defined driving cycle, calculate the energy required for braking. We have considered The US06 which is a high acceleration aggressive driving schedule that is often identified as the "Supplemental FTP" driving schedule. The chart is downloaded from https://www.epa.gov/vehicle-and-fuel-emissions-testing/dynamometer-drive-schedules…

Explain the various applications of Power converters in an Electric vehicle. For Example what type of converter will you use for Horn which requires DC and less than 10V. Likewise come up with different applications. A power converter is an electrical circuit that converts the electrical energy from one form into another,…

Q.1A: Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’.     Speed Control of a DC Motor Using BJT H-Bridge     Description The Bipolar Junction Transistor (BJT) when used for power switching applications, operates as an IGBT. When it is conducting (BJT…

 Q.1:Which types of power converter circuits are employed in electric and hybrid electric vehicle?      The block diagram of a power electronic converter is shown in figure above. It consist of an electrical energy source, power electronic circuit, a control circuit and an electric load. This converter changes one form…

Q.1:What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Mapped Model Dynamic Model Implementation: Model uses a set of steady-state lookup tables to characterize engine performance. The tables provide overall engine characteristics, including actual…

Use ADVISOR tool and simulate the following  1.   For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.   With EV_defaults_in file in Load File tab and cargo mass as 500 kg and all other…

Position control of mass spring damper system: The governing equation for Spring-Mass-Damper (SMD) system is F=mx_dot_dot+cx_dot+kx   where m=mass c=damping coefficient k=spring constant   x_dot_dot=acceleration x_dot=Velocity x=Position   The Laplace Transorm is   F(s)=ms^2X(s)+csX(s)+k(s)=(ms^2+cs+k)X(s)…
