摘要:

A new viewpoint is offered on the construction of a non-Luré-type Lyapunov function for studying the dynamic behaviour of linear systems with a non-linear feedback of the ‘classical’ sector type. The approach makes it possible to show that a particular relation between the parameters defining the Lyapunov function must be satisfied in order to ensure an estimate of the attraction domain closest to the true stability boundary.

摘要:

Discrete-time transfer function simplification by approximate pole-zero cancellation is investigated. Two equivalent ‘rules of thumb’ are derived, which are different from the continuous-time case.

摘要:

Shi and Gao (1986) gave a necessary and sufficient condition for the positive-definiteness of interval symmetric matrices. We point out that their result is not new and the assumptions can be less restrictive.

摘要:

An explicit analytical relationship between coefficients of the characteristic polynomial of open- and closed-loop systems and the elements of the output feedback matrix is presented. This relationship makes the problem of the modal synthesis of a multi-input system much easier.
