We have studied the problem of static competitive routing to parallel queues with polynomial link holding costs. We have established the uniqueness of the NE for a general topology with the BPR cost [22] and have obtained a simple relationship with the globally optimal solution. We have further obtained some explicit results for the special case of affine(More)
SUMMARY This paper investigates the issue of the internal stability of nonlinear delay systems controlled with a feedback law that performs exact input–output, linearization and delay cancellation. In previous works the authors showed that, unlike with the case of systems without state delays, when the relative degree is equal to the number of state(More)
The problem of state reconstruction from input and output measurements for nonlinear time delay systems is studied in this paper and a state observer is proposed that is easy to implement and, under suitable assumptions on the system and on the input function, gives exponential observation error decay. The proposed observer is itself a delay system and can(More)
MRE numerical algorithm and its steady-state solution under particular conditions. A full explanation of this trend is difficult, because of the complexity of the data association process built in the MSPDA algorithm , but one explanation would be that processing the best sensor last improves tracking performance of the sensor system as a whole. Analyses(More)

The problem of state observation for nonlinear systems is of main importance in automatic control. In recent years many contributions have been presented in literature that solve the design problem for classes of nonlinear systems. Most works can be roughly classi ̄ed into two categories. In one the geometrical properties of vector ̄elds de ̄ning the system(More)
A new modeling approach for describing motion of robots in contact with a possibly dynamic environment is presented. The proposed technique allows one to model all those cases in which purely kinematic constraints imposed on the robot end-effector live together with dynamic interactions. Suitable parametrizations are introduced for the environment(More)
This paper explores the possibility of using an asymptotic state observer for the real-time reconstruction of insulin blood concentration in an individual by using only measurements of the glucose blood concentration. The interest in this topic relies on the fact that the glucose measurements are much more economical and faster then the insulin(More)
