1) Obtain the transfer function of a mass spring damper system and use it in the model. Add a PID controller to adjust the force on mass so that its position follows a reference signal. Take m = 3.6; %kg k = 400; %N/m c = 100; %Ns/m The reference signal is shown in the following figure. SOLUTION: I am attaching…

Project : In a laboratory experiment, data of voltage and current has been recorded and the same is attached in an excel file ( Click on this link VI.xlsx ). Read the excel file in the Matlab program and perform the interpolation in the range of -17.3:0.1:0.9. Generate the interactive plot for the interpolated…

    All-electric vehicles, also referred to as battery electric vehicles (BEVs), use a battery pack to store the electrical energy that powers the motor. The batteries are charged by plugging the vehicle in to an electric power source. Although electricity producction may contribute to air pollution, the U.S. Environmental…

  For a defined driving cycle, calculate the energy required for braking. Driving cycle braking energy result: Energy During braking = (1/2)*(Mass*V*V) Mass = 500 KG V = velocity V= (initial velocity - final velocity) Driving Cycle: Time Velocity Mass(KG) 0 0 500 1 0 500 2 0 500 3 0 500 4 0 500 5 0 500 6 0 500 7 0…

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. Load Torque proportional to square of speed (Fan type) T=k*w^2  Here we are using a fan load In this we are using a 4 igbts in h-bridge configuration Matlab simulation time i set was 7 sec For first 0.5 sec the motor…

1.  Which types of power converter circuits are employed in electric and hybrid electric veh s.no Converter Application 1 3 phase inverter (DC - 3 phase AC) 3 phase pmsm or bldc motor drive 2 Chopper (DC - DC) For auxillary controls (head light, audio system, microcontroller) 3 Rectifier or controlled rectifier (AC…

What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?     SOL: IN Mapped model lookup tables are used in terms of data which is given in the spread sheet. this Model uses a set of steady-state lookup tables to characterize engine performance.The…

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. i) Test case 1 cargo weight of136 KG (DEFAULT) Result : This is default cargo mass of 136 kg for 5 FTP cycles it is going for 48.2 KM   ii) Test case…
