Week-7 Challenge: DC Motor Control

Question Main Project – Adaptive Cruise Control (ACC) General Overview: Adaptive Cruise Control Feature for passenger cars allows the host vehicle to adapt to the speed in line with the flow of traffic. Driving in heavy traffic or keeping a safe distance to the preceding vehicle calls for a high level of concentration.…

Mini Project - Vehicle Direction Determination General Overview: Identifying the direction of the vehicle is one of the important & diverse features in Autonomous driving & Advanced Driver Assistance Features. This particular sub-feature of identifying the direction of vehicle is basically identifying the direction…

Aim : Create a MATLAB model of electric car which uses a battery and a DC motor. To check out performance parameters speed, SOC, current with FTP drive cycles. Theory : All-electric cars (EVs), also known as battery electric vehicles, store the electrical energy that powers the motor in a battery pack. The vehicle's…

Aim : To model a fan type load in Simulink and to control its speed by using the PWM method Theory : Pulse Width Modulation The PWM or Pulse Width Modulation is a technique of minimizing the average power delivered by an electrical supply, by properly chopping it up into discrete parts. The average value of supply…

Part A: Q1. Search and list out the total weight of various types of aircrafts.  Ans :  Different types of weight of aircrafts Manufacturer's empty weight (MEW) Also called Manufacturer's Weight Empty (MWE) or Licensed Empty Weight It is the weight of the aircraft "as built" and includes the…

Q.1. For a defined driving cycle, calculate the energy required for braking. Ans : Here we have taken some random values for drive cycle The Excel file attached below and with this data we have plotted a grapg between time and speed(mph). The speed mph converted into mps for calculation Calculations where, Mass = 1000Kg…

  Q1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. Ans : H- Bridge Circuit  In general H- Bridge is a rather simple circuit, containing four switchimg elements, with the load at the center, in an H-like configuration The directions of current flow in H-bridge circuit are shown…

Q.1  Which types of power converter circuits are employed in electric and hybrid electric vehicle?    Ans : The three type of power converter which used in electric and hybrid electric vehicle are  DC to DC converter AC to DC converter DC to AC converter DC to DC Converter : A DC to DC converter…

Q.1 What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type? Ans : The difference between mapped and dynamic model of engine, motor and generator is mapped model is where data point are pre define in lookup tables. The engine, motor and generator torque…

Q1.   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. Ans :  Following step are follow in advisor tool  First step is open Matlab and extract advisor.m file  Tyep advisor in command…

Q.1. Implement control logic of a “washing machine” using Stateflow as per given sequence:  If the power supply is available, the system gets activated  If the Water supply is not available, stop the process & indicate through LED Soaking time should be 200s followed by Washing time of 100s. Then…

Aim : 1.Make a Simulink model of Doorbell using solenoid block           2. Use a thermistor to sense the temperature of a heater & turn on or turn off the fan 1.Simulation Model For Doorbell Model Explanation : Firstly block require for this model is pulse genrator, switch,…
