Project - Data Handling and Interpolation

Here the Speed control of a DC motor is either done manually by the operator or by means of an automatic control device. This is different to speed regulation where the speed is trying to be maintained or regulated against the natural change in speed due to a change in the load on the shaft so  the speed can be varied…

  PROJECT: DESIGN OF AN ELECTRIC VEHICLE     Theory: An electric vehicle(EV) is defined as a vehicle that uses an electric motor or a traction motor for propulsion instead of internal combustion used by conventional vehicles. Electric vehicle use electricity for power instead of fossil fuels like conventional…

[1] ANS: Considering a drive cycle with various braking intervals and hence calculating the braking energy required at corresponding braking interval. Consider mass of vehicle m = 1200 Kg. We know the braking energy when brakes are applied while vehicle is in motion  is given by Eb=1/2×mv2   DRIVE CYCLE…

DC-DC Converter DC-DC converter is an electronic circuit that converts DC voltage from one voltage level to another. It can be step up or step down of voltage. This type of converter is also known as chopper. The electric components inside the vehicle vary in their voltage requirements, with most running on much lower…

[1].A. Ans: 'Speed control of a DC motor using BJT H-bridge. H-bridge:In general an H-bridge is a rather simple circuit,containing four switching element,with the load at the center, in an H-like configuration.     The basic operation of the H-bridge circuit diagram are given below.  …

[1] Ans: Power Electronic Converters: - In Electric and Hybrid Electric Vehicles (EV/HEV), the power electronic converters are considered as the key elements that interface their power sources to the drivetrain of the EVs. In order to design highly efficient converters for the EV’s power system, advanced DC/DC…

[1] Ans: 1st i am explain diffrance between Mapped model and Dynamic model Dynamic model :- represent the actual component Mapped model :- Run based on data even in the lookup table (Run faster) (Give available input)   How can you change model type? How can you change model type? For EV For Motor-Generator…

[1] Load the ADVISOR TOOL from the matlab command window and select metric system, and load EV_default_in file and change the cargo weight to 500 and keeping the remaining variables same and hit continue to load the drive cycle page. for our requirement, we need to use FTP based cycle select the following and hit 'run'…
