Week-11 Challenge: Braking

CASE 1:  For a defined driving cycle, calculate the energy required for braking: BRAKING:  When applying brakes to a car, kinetic energy is converted to heat and then dissipated into the environment via both radiation and convection. But, momentum is transferred to the earth. The act of breaking…

  SPEED CONTROL OF A DC MOTOR USING BJT H- BRIDGE: AIM:        To run MATLAB demo Speed control of a DC motor using BJT H-bridge and to modify the model such that armature current doesn’t shoot up when motor changes direction from forward to reverse.  MATLAB DEMO:    BJT:     Bipolar junction transistor is a device in…

1.TYPES OF POWER CONVERTER CIRCUITS USED IN ELECTRIC AND HYBRID ELECTRIC VEHICLE: Rectifier Inverter Chopper            RECTIFIER:    Rectifier is an electronic circuit which converts the Alternating current (periodically reverses the direction)into direct current(flows in single direction).In a electric and hybrid electric…

CASE 1: MAPPED AND DYNAMIC MODEL: Powertrain Blockset provides two types of combustion engine models: mapped and dynamic. When we have an data based on motor or engine we can map the data in powertrain blockset and we can run the simulation based on the previous data that we mapped on the powertrain blockset,whereas in…

AIM:            To Plot a function  yx=(x-1)*(x-3)^2*(x-9)^2 using basic Simulink blocks.  SIMULINK:          Simulink is a MATLAB based graphical program  for modeling.Simulink blocks in MATLAB provides the interface for the function callers…

AIM :           To calculate the enthalpy,entropy,specific heat of the species in the thermodynamic data file and to write a function which extracts the 14 coefficients using matlab. ENTHALPY:          Enthalpy is a thermodynamic quantity equivalent to the total heat…

AIM:          To optimise the stalagmite function and to find the global maximum of the function using matlab   OPTIMIZATION:           It is the process, or methodology of making something (such as a design, system, or decision) as fully perfect, functional,…

AIM:          To fit the curve in the linear and cubic polynomials for cp data using matlab.   CURVE FITTING:           It is the process of constructing a curve that has the best fit to a series of points possibly subject to constraints. DEGREE OF POLYNOMIALS:…

AIM:          To solve the second order ordinary differential equation for simple pendulum using matlab. SIMPLE PENDULUM:                                                 …

AIM:           To calculate the thermal efficiency and visualizing the p-v diagram of an otto cycle using Matlab. OTTO CYCLE:           Otto cycle is one of the gas cycle which is used in the spark ignition internal combustion engine now a days.        …

AIM:        To simulate a robotic arm movement based on kinematics using matlab. KINEMATICS:         Kinematics is a branch of machanical science which deals with the study of motion such as velocity,acceleration, momentum etc without any force .         e.g)throwing…
