Online Correction of Encoder Errors by 54321llyyxx is a document available to read on EtoBox.
This paper presents methods for online estimation and correction of systematic errors in sinusoidal outputs from incremental position encoders, which are crucial for precise angular position measurement in motion control applications. Two main methods are proposed: one using a scalar error model that operates continuously, and another that updates error parameters iteratively over one full revolution of the encoder. The proposed Harmonic Error Correction (HEC) method utilizes a nonlinear observer to adapt e
