High speed processing of encoder information by using a dual-resolution approach

A novel high-speed, resolution step-up strategy for high precision control system is proposed in this manuscript. Control precision and speed will be limited by the decoder´s circuit if an incremental encoder is used as a device providing positioning feedback. A resolution step-up method is designed and proposed in this paper to address this issue. By using data fusion between measurement from original sensor and outputs of proposed circuit, controlled object´s speed and accuracy could be improved.
