![]() ![]() Compared to the regenerative brake and rheostatic brake, the proposed braking system has a powerful braking torque and shorter reaction time. This provides a smoother and more accurate motor control than sinusoidal commands with Hall feedback. When the motor receives a brake command, the controller changes the inverter-switching sequence to generate reverse torque and a magnetic field to complete the driving or braking function using field-oriented control (FOC). It calculates the rotor position angle of the motor by detecting variation in the stator current and completes a closed-loop control. This research proposes a sensor-free, integrated driving and braking control system that uses a space-vector-pulse-width module to synthesize stator current by purpose.

Output of current model is actually a little bit slower than the ramp generator. ![]()
