1.What is the difference between the mapped and dynamic model of engine, motor, and generator? How can you change the model type?   MAPPED models: Mapped models are used when the behavior of a particular model is not of our interest and can be modeled with predefined values in the form of lookup tables. eg: mapped motor:…

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. Answer :-      BJT H-BRIDGE:                 An H-bridge is an arrangement of transistors that allows a circuit full control over a standard electric DC motor.…

Q1. For a defined driving cycle, calculate the energy required for braking. Answer :-   Deceleration conditions are similar to acceleration conditions. Acceleration increase in speed and deceleration is a reduction in speed. So similar way to calculate braking power. Where M= mass of the vehicle.  …
