Title
Distributed Optimal Fault Estimation and Fault-Tolerant Control for Interconnected Systems: A Stackelberg Differential Graphical Game Approach
Abstract
This article addresses the distributed optimal fault estimation (FE) and fault-tolerant control (FTC) issues under the bidirectional interaction between a possibly faulty interconnected system and its associated diagnostic interconnected observer. The proposed methodology is based on a framework, named <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Stackelberg differential graphical game</i> , in which the interconnected observer and its corresponding interconnected system are formulated as two graphical games, and they, respectively, play the role of the follower and leader to make <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sequential</i> decisions of the FE and the FTC. Such a framework allows us to fully reveal the property of the bidirectional interaction, based on which a distributed optimal FE and FTC scheme is developed. Moreover, a new concept named <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">interactive Stackelberg equilibrium</i> is proposed, where, to reach this equilibrium, an auxiliary controller is suitably designed for each subobserver. In this way, this auxiliary controller can cooperate with other auxiliary controllers of subobservers, and noncooperate with controllers of subsystems, which helps to achieve the distributed optimal FE and FTC goals.
