✦ Synopsis

In this paper we de®ne two new propertiesÐlinear observability and L-observability Ðto aid the study of overspeci®cation and unidenti®ability in quasi-linear and non-linear state space time series. Various equivalence results are proved and illustrated and some general properties of observable and unobservable processes are derived. The results are often proved by using graphical methods (in¯uence diagrams) for manipulating conditional independence statements embedded in the new de®nitions.

The tracking control problem for a class of non-linear systems with control and state constraints is considered. A predictive control approach is used to derive the constrained optimal control law. The unique structure of the controller allows a parameter to be continuously tuned on-line via the sol

## Communicated by M. Renardy The steady-state problem of the non-linear reaction-diffusion system is considered. The existence of positive steady-solutions is established by using a fixed point theorem in ordered Banach space. The uniqueness of ordered positive steady-state solutions and an appl

This paper addresses the problem of stabilization of a class of internally passive non-linear time-invariant dynamic systems. A class of non-linear marginally strictly passive (MSP) systems is defined, which is less restrictive than input-strictly passive systems. It is shown that the interconnectio

The control of uncertain non-linear discrete-time systems having stochastic cone-bounded non-linearities is considered. First, a quadratic performance bound and a guaranteed-cost optimal state feedback controller are derived. Then, an auxiliary system is introduced. It is shown that the quadratic op

It is known that large classes of approximately-"nite-memory maps can be uniformly approximated arbitrarily well by the maps of certain non-linear structures. As an application, it was proved that time-delay networks can be used to uniformly approximate arbitrarily well the members of a large class
