  Q. Obtain the transfer function of a mass spring damper system and use it in the model. Add a PID controller to adjust the force on mass so that its position follows a reference signal. Take m = 3.6; %kg  k = 400; %N/m c = 100; %Ns/m  AIM :    We Create a model of mass spring damper system using…

Q01. Search and list out the total weight of various types of aircrafts.      Aircraft Gross Weight: The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation. An aircraft's gross weight…

Q01.  For a defined driving cycle, calculate the energy required for braking. Solution: Under the condition of braking, some amount of energy is required to do the same as that of energy required for accelerating the vehicle. Hence to calculate energy, we use the acceleration energy equarion, Calculating the…

Q01.        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…

 Q01.  Which types of power converter circuits are employed in electric and hybrid electric vehicle?   Ans :-  Power Electronic Converters: In EV’s and HEV’s, the power electronic converters are considered as the key elements that interface their power sources to the drivetrain of EVs. In…

Q1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Ans: Powertrain blockset provides two types of combustion engine models:mapped and dynamic.  Mapped Engine :  1.Mapped engines represent macro engine behaviour as a set of lookup tables(brake…
