Complex control applications require a capability for accommodating faults in the controlled plant. Fault accommodation involves the detection and isolation of faults, and taking an appropriate control action that mitigates the effect of the faults and maintains control. This requires the integration of fault diagnostics with control, in a feedback loop. This paper discusses how a generic frame...

1. Motivation The Dynamic Walking community has rightly focused on the aspects of gait that can be modeled, predicted, and explained by the mechanics of multibody systems. Sensory feedback is assumed to play a role in walking, but generally via machine-like, relatively low-dimensional feedback control mechanisms in a virtually noise-free system. Human beings, however, are “perception-action” sy...

Formation control ideas for multiple spacecraft using the virtual structure approach are presented. If there is no formation feedback from the spacecraft to the virtual structure, the spacecraft will get out of formation when the virtual structure moves too fast for the spacecraft to track due to spacecraft control saturation or the total system must sacrifice convergence speed in order to keep...

This article deals with the regulation of water 6ow in open-channels modelled by Saint-Venant equations. By means of a Riemann invariants approach, we deduce stabilizing control laws for a single horizontal reach without friction. The stability condition is extended to a general class of hyperbolic systems which can describe canal networks with more general topologies. A control law design base...

Starting from states near to a closed set S we want to steer S and to stay always close to S. Unfortunately, open-loop controls are very sensitive to disturbances and can lead to very bad practical results. For that reason, we propose an approach for constructing a discontinuous feedback control law that asymptotically stabilizes the system in a neighborhood of the set S.

In this research, a model is established to represent a supply chain, which consists of one manufacturer and two retailers. The price-sensitive demand model is considered and the price game system is built according to the rule of bounded rationality as well as the entropy theory. With the increase of the price adjustment speed, the game system may go into chaos from the stable and periodic sta...

then, under mild restrictions on Q, thc resulting feedback system is a "good" system by most classical criteria. An equally significant result is as follows [2 I. Given a feedback control law u = -k'x for the system (I), which is known to yield an asymptotically stable closed-loop system, then a ncccssary and sufficient condition for this control law to bc optimal with respcct to a performance ...

Algebraic characterizations are presented for the existence of fixed modes of a linear closed-loop system with decentralized feedback control. The class of controllers for whch tixed modes are present is extended beyond that currently known.
