Resolver (RSLV) eTPU Function
AC Motor Control
eTPU Function Set
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.
