  • contour posistioning system (cps) - a method of estimating electric vehicle battery capacity and distance travelled accurately using various types of elevation profiles and data
    A specific technique used to calculate the energy required in EV to travel between two destinations by considering the mapping and contour behaviour.

  • data-driven controller for direct generation of inventer switching commands in an electric motor drive system
    Permanent Magnet Synchronous Motors (PMSMs) are widely adopted in
    electric vehicles, robotics, and industrial automation due to their high efficiency
    and torque density. However, conventional control architectures (such as Field Oriented Control or FOC) typically rely on complex multi-stage processing. This includes coordinate transformations, cascaded current controllers, and explicit modulation stages.
