ÜÜnyelioglu, K. A.Özgüner, Ü.Özgüler, A. B.2016-02-082016-02-0820000018-9286http://hdl.handle.net/11693/25101This paper considers the notion of decentralized fixed zeros for linear, time-invariant, finite-dimensional systems. For an N-channel plant that is free of unstable decentralized fixed modes, an unstable decentralized fixed zero of Channel i (1 ≤ i ≤ N) is defined as an element of the closed right half-plane, which remains as a blocking zero of that channel under the application of every set of N - 1 controllers around the other channels, which make the resulting single-channel system stabilizable and detectable. This paper gives a complete characterization of unstable decentralized fixed zeros in terms of system-invariant zeros.EnglishClosed loop control systemsDecentralized controlMatrix algebraOptimal control systemsPoles and zerosSystem stabilityTheorem provingDecentralized fixed zerosTransfer matrixLinear control systemsArticle10.1109/9.827373
