The RSLV function provides the eTPU with the
capability of tentatively processing the signals from the
resolver hardware. The RSLV function running on the
eTPU is able to calculate the position and speed of a
connected resolver without requiring any computational
load on the CPU.
For computation of position and speed, the RSLV function uses the Angle Tracking Observer algorithm.
The Angle Tracking Observer algorithm is based on a closed-loop space-state system minimizing the
difference between a computed angle and the angle read from the resolver signals.
