Week-11 Challenge: Braking

   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…

For a defined driving cycle, calculate the energy required for braking. Link to sheet       By using kinetic energy formulae in sheets in a cell..we can calculate energy required for each individual velocity      By considering the zero velocity as braking velocity reference we can…

Make a Simulink model of Doorbell using solenoid block with the following details:   In the above arrangement, when the switch is closed the electromagnet receives electrical power from the battery and pulls the metal arm to hit the bell producing sound.  Create a situation where the switch is closed…

Write a function that extracts the 14 co-efficients and calculates the enthalpy, entropy and specific heats for all the species in the data file. You will be reading this file NASA thermodynamic data(Tip: use fopen and fgetl). The formulae are shown below.  Here R is the universal gas constant, T is the temeprature The FIRST 7…

Speed control of a DC motor using BJT H-bridge the default simulation  adding inductor in series to armature adding inductor in series to h bridge changing duty cycle from 75% to 50% so whats happening? default condition : due to sudden change in voltage or direction, high torque due to inertia and High inrush currents…

1.   Which types of power converter circuits are employed in electric and hybrid electric vehicle?                                                           …

Write a code in MATLAB to optimise the stalagmite function and find the global maxima of the function.  And Plot graphs for all 3 studies and for F maximum vs no. of iterations. % Genetic Algorithm % This example shows how to create and manage options for the genetic % algorithm function |ga| using |optimoptions|…

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

1. 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: Aim: To verify whether the vehicle can travel for 45km with cargo mass of 500kg for EV_ defaults simulated vehicle in advisor tool Procedure: 1.…

Aim: To Write a program in Matlab\\Octave that will simulate the pendulum motion, just like the one shown in the start of this challenge. Apparatus: Matlab Procedure: 1. create clear, close commands inorder to clear the tabs and erros 2. create ode_func based on the equation given 3. use these function to create pendulum…
