Differently from previous studies of tag-based cooperation, we assume that individuals fail to recognize their own tag. Due to such incomplete information, the action taken against the opponent cannot be based on similarity, although it is still motivated by the tag displayed by the opponent. We present stability conditions for the case when individuals play unconditional cooperation, unconditi...

On the basis of the Passivity Theorem, this paper provides a new approach to stability analysis for multi-loop control systems. The destabilizing effect of interactions of a multi-input multioutput system is studied using the passivity index. The decentralized unconditional stability condition, which implies closed-loop stability of decentralized control systems under control loop failure, is d...

Fractional order diffusion equations are generalizations of classical diffusion equations which are used to model in physics, finance, engineering, etc. In this paper we present an implicit difference approximation by using the alternating directions implicit (ADI) approach to solve the two-dimensional space-time fractional diffusion equation (2DSTFDE) on a finite domain. Consistency, unconditi...

This paper provides a new approach to decentralized failure-tolerant control using passivitybased stability conditions. A controller design method is developed to achieve both decentralized unconditional stability (a transformed passivity condition) and user-specified H2 performance. The control synthesis problem is solved by using successive semidefinite programming. The proposed method is ill...
