Project 2

In this project FTP75 drive cycle is used to calcualte the energy analysis.

longitudinal driver has the input and output units. refernce speed and the output speed from the unit is fed back to the driver system as feedback speed to get the exact result from the unit.

it uses the PWM control voltage to generate the pulses to trigger the H-bridge convertor and the convertor produces the output power that is delivered to the motor. with help of the power the motor speed varies and it is controlled by that.

Rotor of the motor is connected to the simple gear and the simple gear is connected to the wheel of the vehicle. and uses the vehicle body to calculate the exct result.

in addition to the above process the energy analysis subsystem was used. in this part derivative block, integrator block, gain block and the magnitude square blocka nd the eulers block, addition block are used to calculate the total energy.

In this energy analysis subsystem is used to calculate the total tractive force by adding the rolling resistance force, hill climbing force, aerodyanmic force, acceleration force is used to claculate that. i attach the snap of the subsystem.

in this project the vehicle body weight is taken as 600kg and other values are taken.
