Week-7 Challenge: DC Motor Control

  ANS :-- OBJECTIVE  MATLAB model of electric car which uses lithium ion battery and suitable motor. System level configurations & Model parameters 1) DRIVE CYCLE we give FTP75 drive cycle to run the model   2) DRIVER  vehicle speed control using PI controller and generate brake and accelerator commands   in it --PID The…

ANS : AIM :  Design of an Electric Rickshaw using MATLAB Simulink.   ABSTRACT : In this project, we going to build the MATLAB model of the ELECTRIC RICKHAEW by using a PM brushed type DC motor and a suitable Lithium-Ion battery for the motor. Before that, we will know about what is Electric RICKHAEW, how it's works and…

ANS :   An Electric Vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery, solar panels, fuel cells or an electric generator to…

part A ) ANS : Weight is a major factor in airplane construction and operation, and it demands respect from all pilots and particular diligence by all maintenance personnel. Excessive weight reduces the efficiency of an aircraft and the available safety margin if an emergency condition should arise. The total weight is…

  AIM: For a defined driving cycle, calculate the energy required for braking. To define why electric motor can’t develop braking torque at high speed similar to starting and how electric and mechanical brakes are coordinated. To make a MATLAB program which plots contour of given motor speed, torque and efficiency values. …

ANS: A)Working of H-bridge model: Here H-bridge  DC chopper circuit is designed to control the speed of the motor. IGBT acts as BJT in power switching devices. Four IGBT switches are used for inverting the DC voltage 0 to 240 v supply.The current flows from collector(C) to emitter(E). The gate are controlled by the pulses(0…

ANS :   Electric Vehicles: An electric vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery, solar panels, fuel cells or an electric…

1) Ans ; Mapped models are used when the behavior of a particular model is not of our interest and can be modeled with predefined values in the form of lookup tables. eg: mapped motor: in the below model values are taken from experiments or old data Implements a mapped motor and drive electronics operating in torque control…

Q 1) ANS : ADVISOR, NREL’s Advanced VehIcle Simulator, is a set of model, data, and script text files for use with Matlab and Simulink. It is designed for rapid analysis of the performance and fuel economy of conventional, electric, and hybrid vehicles.  ADVISOR also provides a backbone for the detailed simulation…
