The passivity equation is the main necessary condition of passivity and dissipativity of nonlinear control system. The paper presents necessary and sufficient conditions of its solvability with respect to some nonnegative storage function. These results can be a basis for further investigations on passivity of controlsystems. Furthermore, they have applications in adaptive control.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

The complex oscillations appearing in the system with clearance between the drive and driven sections of mechanical transmission are considered and the mathematical model is proposed for certain assumptions. It is shown that the model possesses a resemblance to the Ulam map and has regular and irregular behavior that is typical for the motions of the driven section in system with ‘yawn’.

In this paper we propose an algebraic realization of the empty matrix concept which is appropriate for system-theoretic applications. This realization differs considerably from the realization currently implemented by The Mathworks, Inc. within their MATLAB program. We demonstrate by repeated example the utility of our realization of the empty matrix concept, and through these same examples indicate the deficiencies of the current MATLAB realization of this concept. These examples fully delineate how the empty matrix concept can be utilized to transparently handle static and/or single vector input, single vector output systems within the more general context of dynamic, two vector input, two vector output systems.
