ROBUST PID CONTROL FOR BLDC MOTOR CONTROLLER

摘要

When controlling an air compressor (13) for a pneumatic braking system on a large hybrid commercial vehicle (e.g., a bus, a package delivery truck, etc.), PID control of an air compressor motor (12) is employed during normal system operation such as when the motor shaft is spinning, and state machine control is employed during startup or upon a system disturbance such as a shaft seizure or stall. In this manner, stalling events that occurs due to PID control inability to correct for unexpected disturbances are mitigated by employing state machine control.
