Vibration Compensation of Delta 3D Printer with Position-varying Dynamics using Filtered B-Splines
Nosakhare Edoimioya, Cheng-Hao Chou, Chinedum E. Okwudire
The delta robot is becoming a popular choice for the mechanical design of fused filament fabrication 3D printers because it can reach higher speeds than traditional serial-axis des…
A physics-guided data-driven feedforward tracking controller for systems with unmodeled dynamics -- applied to 3D printing
Cheng-Hao Chou, Molong Duan, Chinedum E. Okwudire
A hybrid (i.e., physics-guided data-driven) feedforward tracking controller is proposed for systems with unmodeled linear or nonlinear dynamics. The controller is based on the filt…
Combined servo error pre-compensation and feedrate optimization -- with application to a 3D printer and precision motion stage
Heejin Kim, Chinedum E. Okwudire
Servo error pre-compensation and feedrate optimization are often performed independently to improve the accuracy and speed of manufacturing machines. However, this independent appr…
