Improvement of SDE for Linear Encoder with an Auto-Compensation System
Xinji Lu, Fan Yang, Artūras Kilikevičius · Mechanika · 2024
Sub-divisional errors (SDE) of linear encoders adversely affect mechanical equipment performance. Existing compensation methods often entail high costs or increased complexity. This research introduces an adaptive auto-compensation system for SDE reduction by minimize the factors of DC-offsets, deviation in amplitudes and phase disparities. The system has the advantage mitigate errors without significant additional expenses or complexity. Theoretical analysis of SDE and the experimental setup are discussed, alongside analytical data demonstrating the system's effectiveness.
