Single-pedal regenerative braking (Ather 450X reference)

An electric scooter drive where lifting the throttle brakes the vehicle and returns energy to the battery.

Aim

Model a PMSM scooter drive with field-oriented control and a supervisory controller that blends drive and regenerative braking from a single throttle.

What you’ll learn

How single-pedal driving maps throttle to drive or regen torque
Field-oriented current control of a PMSM
Battery and DC-link energy flow during regeneration
Average-value vs switching (SVPWM) inverter models and when to use each
