摘要:

Sufficient conditions are established for the controllability of non-linear delay systems with an implicit derivative. The results are obtained using the measure of the non-compactness of a set and the Darbo fixed-point theorem.

摘要:

The decentralized technique is used to investigate the stability of the large-scale system in the presence of each isolated subsystem with optimal model matching. The optimal model matching of the isolated subsystem is first obtained by applying the parameter optimization technique to minimize a meaningful measure of model matching, then a sufficient condition is derived such that the compensators stabilize the overall system using a functional analysis technique. Moreover, a necessary and sufficient condition for the existence of such a compensator is derived by using the Nevanlinna-Pick interpolation. Finally, an optimal design algorithm is proposed to attenuate the effect of interconnection between subsystems.

摘要:

A new algorithm is presented for the identification of non-linear lumped time-invariant SISO systems. The method is based on differentiation properties of the exponential Fourier series and can be used to identify a wide class of systems. Identification of two specific systems is studied. An illustrative example is provided which shows that the algorithm gives accurate parameter estimates

摘要:

The influence of non-linear elements on the exponential stability of a subclass of semistate systems is investigated. It is shown that some constraints on non-linearities can provide information on the behaviour of all phase coordinates if, initially, only the partial stability behaviour is known.

摘要:

We give a sufficient condition for the robust stability of the discrete systemXk+1, = (F+E)Xkwhere the perturbationEis bounded (|E| ≤U). A necessary and sufficient condition is derived in the case whereFis a positive or a negative matrix andU= ε|F|. The stability of interval matrices is also considered. Numerical examples are given for illustration.

摘要:

A likelihood ratio test is used to detect the portion of the prediction error variance caused by changes in parameters. It results in a simple rule for adjusting the dispersion factor in the parameter covariance matrix. The adaptation rule given by Jazwinski (1970) is shown to be a special case of one derived
