I'm looking to get some feedback on a test report we have created for FAST (observer used in InstaSPIN-FOC). We'd like to know if it is helpful, not helpful, or any areas of improvement.
If you are interested please post or message me your email address and I will select a few for early viewing. Thanks!
"This document describes the performance specifications for the FAST observer (which is part of the InstaSPIN-FOCTM software) running in ROM on InstaSPIN-enabled C2000 microcontrollers. It should be noted that this test specification encompasses the FAST algorithm only and does not include the Auto-ID algorithm, PowerWarpTM, or other aspects of the InstaSPIN-FOC software.
FAST is based on a unified motor model which is compatible with PMSM, IPM, ACIM, and even stepper motors. However, the fact that it can be used to control so many different motors in so many different configurations makes it impossible to specifically document its performance in every scenario. In an effort to reduce the permutations required for such an effort, this document focuses only on FAST performance as applied to a specific PMSM motor. As such, this document can only serve as an indication of FAST performance for other motors in different operating scenarios. But from a review of the data in this document, it will become apparent that there are trends related to the algorithm itself which will affect how FAST operates in other scenarios as well.
It should also be noted that this document applies only to the fixed-point implementation of FAST which is currently included in ROM on select C2000 devices in the Piccolo family. Every effort has been made to separate the performance of the algorithm itself from the specific hardware it is implemented on. "
