  • Simultaneous stabilization and simultaneous pole-placement by nonswitching dynamic compensation

    In this paper, motivated by questions in fault tolerance, we investigate the existence of a compensator which simultaneously renders a given r -tuple of plants internally stable. Sufficient conditions are derived for simultaneous pole-assignability of the generic r -tuple by dynamic output feedback, which are also shown to... View full abstract»

  • Weak connections, time scales, and aggregation of nonlinear systems

    If nonlinear subsystems with continuous equilibria are weakly connected, their local behavior is fast compared with the systemwide behavior caused by the connections. The slow behavior is described by an aggregate model which appears as a slow subsystem in the singular perturbation form of the model. In this way earlier linear aggregation results by Simon et al. in economics and slow coherency res... View full abstract»

    Since its inception, the IEEE Systems, Man, and Cybernetics Society has had an increasing influence on the field of large scale systems, particularly as these relate to areas of human interaction. The purpose of this paper is to provide an overview of some of the major areas of activity by SMC in large scale systems. The work of others has been taken liberally and full credit is due the many excel... View full abstract»

  • Propagation of conic model uncertainty in hierarchical systems

    Conic sectors are used for analysis of stability and modeling uncertainty propagation in interconnected systems with a hierarchical structure. For large systems that can be readily decomposed into sparsely interconnected groups subsystems, sub-subsystems, sub-sub-subsystems, etc., analysis is greatly facilitated: formulas for conic uncertainty propagation and stability analysis are applied success...

  • Decentralized control of traffic networks

    An arbitrary interconnected network of intersecting streets with one-way traffic flow is considered in which some or all intersections are assumed to be operating at maximum capacity. In this case, it is desired to find a robust decentralized controller at each traffic intersection, so that for all perturbed external traffic flow sources/sinks, the resulting perturbed queues at each intersection a...

    This paper surveys in a tutorial fashion theoretical and applications aspects of the continuation method for the solution of large scale system engineering problems. The continuation method is motivated and defined. The existence of the method is formulated in terms of degree theory a la Algebraic Topology. Examples are given throughout the paper and applications to engineering and economic proble... View full abstract»

    The testability condition for single branch-fault of an analog network is given. Then several necessary and sufficient conditions for this testability condition are provided and their proofs are shown in detail. These conditions have great applications in the testability design as demonstrated in the examples. View full abstract»

    In the present paper we report on the status of stability of complex dynamical systems. We consider those systems which may be viewed as an interconnection of lower order subsystems. We emphasize those types of results which are phrased in terms of the stability properties of the subsystems and in terms of the qualitative-properties of the system interconnecting structure. We consider both Lyapuno... View full abstract»

    This paper is concerned with modeling and control strategy interaction in a multimodel context. The role of the observability structure in multiple decisionmaker (DM) problems is examined. A procedure is developed for generating multimodel solutions based on certain deterministic information patterns. This is achieved by first explicitly identifying the state space structure induced by the observa... View full abstract»

  • Solution of piecewise- linear ordinary differential equations using waveform relaxation and Laplace transforms

    Piecewise-linear (PWL) functions are frequently used to describe the nonlinear branch equations of nonlinear devices in LSI circuits. New techniques for the solution of the differential equations describing the behavior of piecewise-linear circuits will be presented. These techniques are based on the waveform relaxation method to decouple the system equations and Laplace transform techniques to so... View full abstract»

    The marketing networks of third-world countries are large systems having many markets and many agents. The dynamic behavior of one form is modeled in this paper by examining the actions of the traders. Recursive analysis yields time series in all prices and commodity flows. The network has a unique equilibrium state. Under certain conditions on supply and demand elasticities, that equilibrium stat... View full abstract»

    In this paper, we present a new methodology for custom VLSI layout which aims at a low turnaround time and a high quality of design. VLSI circuits are highly complex, and to speed up the design process we exploit the hierarchical structure of a design, splitting the problem domain into several levels. The process of layout at each level is divided into steps such as placement of rectangular blocks... View full abstract»
