SYSTEM AND METHOD FOR TRANSIENT-BASED MOTOR SPEED ESTIMATION WITH TRANSIENT EXCITATION |
摘要 |
Control systems and speed estimation systems are presented having a transient-based speed estimation system that provides a rotor speed estimate based on a measured speed-related motor transient signal, and a transient excitation system which selectively modifies at least one switch control signal to excite the measured motor transient.
