Dynamic error compensation of high speed
WebDynamic performance of high speed, high resolution digital-to-analog converters (DACs) is limited by distortion at the data switching instants. Inter-symbol interference (ISI), imperfect timing synchronization and clock jitter are all culprits. A DAC output current controlled by an oscillating waveform is proposed to WebA dynamic model for a simple robotic truss with dual actuation and control strategies for it, including the possibility for distributed control, are developed. The model is used to show that a dual actuated robotic truss can achieve a dynamic stiffness of over 200 N/micron (1.14 x 10 (exp 6) lb/in.) which is sufficient for precision machining.

WebJan 1, 2014 · It is concluded that higher speed causes additional deflection, which is not compensated. Pereira and Hocken [4] proposed a complex method of compensation for dynamic errors of CMM scanning probes. This method is based on investigating the effect of centripetal acceleration during circle form scanning with the open loop mode. WebSep 1, 2024 · In order to reduce the contour error, a compensation method utilizing a real-time amplitude control in the elliptical vibration cutting process has been applied. In the proposed method, the dynamic motion error along the depth of cut direction is detected by utilizing the precise linear encoders installed on the feed drive system.
