VOLTAGE ESTIMATION FEEDBACK OF OVERMODULATED SIGNAL
摘要
A voltage estimation system for motor control feedback is described. The system may include one or more control modules which may generate voltage commands. An overmodulation or "clipping" module receiving a voltage command can generate a clipped voltage. Rather than measuring directly, a voltage estimator may estimate the clipped voltage based on the duty cycle command to the inverter. This estimated voltage may then be used by a flux estimator to estimate a flux value. Other embodiments are described and claimed.
