Non‐sequential MIMO QFT control of the X‐29 aircraft using a generalized formulation

摘要: This paper presents a generalized formulation for multi-input multi-output (MIMO) quantitative feedback theory (QFT) based controller design and analysis, its application to the control of X-29 aircraft. The is on more general structure, where input output transfer function matrices are included provide additional degrees freedom in decentralized MIMO QFT that facilitates exploitation directions designs. captures existing approaches fully populated provides directional logic involving plant alignment properties their multivariable poles zeros. Horowitz's Singular-G methodology placed context analysed redesigned using non-sequential formulation, demonstrating utility. results highlight fundamental trade-off between stability performance classically formulated methodologies, elucidate designed controllers validate recent contributions QFT.
