Cross-coupled Contour Tracking Control of Direct Drive H-type Platform Based on Real-time Contour Error Estimation

Cross‐coupling control strategy based on intelligent adaptive control for cross‐shaped dual‐axis linear motors

“…[21] estimated the contour error through the secondorder expansion of the Taylor formula based on the approximation of the close circle. Syh-Shiuh Yeh et al [22] performed contour error estimation for free trajectories based on tangent approximation. However, all the above methods using the tangent circle and tangent line estimation only refer to the position of a point for the calculation.…”
