Solution: The TF is obtained from the given Spring mass damper system and modelling is done: Note: The Modelling parameters are Fixed step size of 0.01 with solver as ODE4(Runga-Kutta) and Input as Pulse generator of amplitude 1 and period 10s and width 50%. % PID design for Spring mass system   m=3.6; k=400;…

Solution 1: In the Advisor tool, EV_defaults i.e, pure EV vehicle is selected and cargo mass is changed to 500kg, total weight amounting to 1508kg with all other parameters kept as default as shown: Now the drive cycle is selected as FTP. As each drive cycle of FTP is around 17km, so 3 such drive cycle is added as…

Ans 1: Mapped Model also called the static model is the one where we have predefined data of motors/gen in the form of look up table whereas the dynamic model is the one where we represnt the actual components using the actual motor/gen data. For eg inverter model, controller can be altered/control as per the requirement…

Ans 1: There are basically 4 types of main Power COnverter circuit in Power Electronics domain. Their features and application in EV and HEV are described below: i.) AC to DC Converter or Rectifier This type of converters are used when we need to convert AC supply to DC. In EV/HEV, battery pack are based on DC so…

Ans 1a) MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’ is explained below. Detailed Explanation of the Above simulation: Here, 5Hp 240V, DC motor is used with fan torque simulated load which follows the square speed law. The H-bridge model is used having 4 IGBT(BJT based with…

Ans 1: The random driving cycle is created in excel for 100s and defined as follows for the Brake Energy Calculation: The Brake energy is calculated by the change in Kinetic energy of vehicle at every instant of braking applies as by the general formula Where m is the mass of the vehicle, lets say 1000kg and Vf and Vi…

Part A: Ans 1: Below is the list of some 100 numbers of Aircraft in three main category; Heavy, Medium and Light.  Here, MTOW means Maximum Take off weight in kg and MLW is the maximum landing weight in tonnes. Type MTOW in kg  MLW in tonnes ICAO Category Antonov An-225 6,40,000 591.7   Heavy Scaled Composites Model 351…

Ans: To model the Electric Vehicle, we must first understand the different significant systems/parts of it. Unlike traditional vehicle, EV requires battery pack and motor with controller for its traction drive in place of Engine. The major components of EV to be used for its MATLAB modelling are as follows a) Battery,…

Ans : Power converters play a vital role in electric vehicles (EVs) in converting and regulating electrical power from one form to another.  Some of the applications of power converters in an electric vehicle are follows: 1. DC-DC Converter: A DC-DC converter is commonly used in electric vehicles to step down or step…
