摘要
Multi-axis coordinated trajectory following is important in CNC machines and metal cutting tools. Recently, flight simulators with electrical actuators have been in increasing demand. However, the coordinate control scheme affects the accuracy of the motion because motors have an insufficient load-capacity relative to the hydraulic actuators. The electronic cam (ECAM) is typically used to perform coordinated control. However, selection of the master may determine potentially very different characteristics of motion. This study proposes an automatic master switching method. The conditions and results of the master switching method for ECAM are detailed. The robustness and stability of the proposed control system is also demonstrated using the well-known structured perturbation analysis tool, andle=V-WA-A-W-AU-MsSAYVA-UUA-U-AABZWDCUEA-AABBYCCYEA-CADVWCCZC-AU-U&_acct=C000050221&_version=1&_userid=10&md5=261b4b6e8efd0af3375bed8a363c973a" title="Click to view the MathML source">μ.
