RESUMO

In this thesis a decentralized methodology for linear state space identification of discrete time, serially interconnected multivariable stochastic systems is proposed. The global system identificationis achieved by means of the individual identification of its subsystems through some state space methods for identification of multivariable systems and time series, among the ones here discussed: Multivariable Output-Error State Space Identification (MOESP), Numerical Algorithms for SubspaceState Space Systems Identification (N4SID), Constrained Least-Squares State Space Identification (CLS-SSI), MOESP-AOKI. Based on the obtained subsystems models a methodology of optimal decentralized control systems that explores the matrices Lower Block Triangular structure is utilized. The combined decentralized stochastic identification and control methodology structured in this study is applied to an interconnected river water quality system, that motivated this work
