摘要：AbstractIn this work, Disk Margin, Maximum Sensitivity, and Vector Margin concepts are extended to stability margin analysis in Finite-Time Convergent Control (FTCC) systems. Next, corresponding algorithms for computing Disk Margin, Maximum Sensitivity, and Vector Margin in FTCC systems are proposed based on the Describing Function – Harmonic Balance Technique and acceptable limit cycle behavior in FTCC systems. Finally, the efficacy of the proposed methodologies is validated on a tutorial example of the FTCC system, and the advantages of using Disk Margin and Vector Margin in FTCC systems over traditional Gain and Phase Margins are demonstrated.
