This paper deals with the linear ∞ filtering problem for a class of regionally stable uncertain nonlinear systems subject to bounded disturbances and measurement noises. The nonlinear systems is represented by differential-algebraic equations where the system matrices are allowed to be rational functions of the state and uncertain parameters. For this class of systems, LMI conditions are proposed for ensuring a prescribed upper-bound on the L2-gain of the input-to-estimation error operator for a given linear asymptotically stable filter. The result is based on polynomial Lyapunov functions. Then, using an appropriate parameterization of the Lyapunov function we extend the analysis result for designing linear filters in a ∞ sense via a convex optimization problem.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

The feedback control structures are required in the presence of any kind of uncertainty. The benefits of the feedback are mainly paid with an excessive bandwidth that amplifies the sensor noise, saturating the actuators. This implies the necessity of design tradeoffs highly transparent from the Quantitative Feedback Theory. Supposing a given uncertainty for a plant, the set of performance and stability requirements will condition the problem solution. Taking advantage of the QFT bound typology and formulation, the contribution of the robust specification values to their simultaneous achievement will be analysed and particularly as regards the challenging task of the controller design.

He is currently the lead modelingand simulation engineer for the JTCTS program.

The Joint Tactical Combat Training system (JTCTS) is a joint Navy/Air Force program to provide enhanced tactical combat training from single-platform warfighting through integration of multi-platform coordinated combat training (surface, subsurface, and air). Key requirements of JTCTS include the use of the Global Positioning system to generate platform position information, simulated platforms and weapons, and a real-time radio datalink to transmit training data within 400 nm of a JTCTS core-capable site, using a distributed simulation architecture derived from distributed interactive simulations. Many design tradeoffs need to be made to implement this system. To enable the meaningful test and tradeoff of various design options, a software model of the JTCTS system was constructed. This discrete-event simulation was implemented entirely in software running on commercial workstations. The model allows the designers to test various software and hardware design implementations and measure their influence on the ''goodness'' of the exercise data. Based on platform attitude and relative position, datalink connectivity can be assessed and various message-passing algorithms tested. The effects of message latency and communications dropouts on dead-reckoning accuracy can be directly measured. Effects of aircraft antenna shading, atmospheric effects on radio frequency propagation, and others can be turned on or off depending on the needs of the particular test, and to support validation of the model. The engineering model was created during the project concept definition;it is being used today in a number of design studies. One, a datalink transmitter power tradeoff, is giving insight into the relationship between the accuracy of after-action reports and the heat dissipation of the datalink components. These simulated exercises are providing both the end-user and the design team with insight into subsystem and operational interactions usually not seen until system integrati

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.

Recent advances in computer networking and control system technologies present an opportunity to improve the capability of naval shipboard control systems. Most existing digital machinery control systems merely replace one-for-one their analog predecessors. These recent advances motivate rethinking the basic role and architecture of shipboard controls. Traditional machinery system control has remained largely separate from combat systems and other ship information systems. Existing machinery control systems have concentrated on four functions: machinery status, control, system stability, and fault response. To implement these functions, custom systems have been designed, built and debugged for each class of ship. This lack of commonality has been expensive in terms of development costs, maintenance costs over the lifetime of the ship, and also the unrealized benefits stemming from prohibitive costs of adapting machinery controls to take advantage of emerging technologies. This paper proposes a new paradigm for developing a shipboard control system based upon a functional decomposition of ships' missions that leads to defining technology independent interface standards. Multiple vendors may be able to independently develop control system hardware and software elements adhering to such interface standards without a priori knowledge of a particular ship application, leading to the ability to develop a total ship control system with low risk by integrating proven hardware and software elements to meet specific ship design requirements. With this new concept, other functions not normally associated with machinery controls are feasible: spontaneous reconfiguration after a damage event, integrated training, condition based maintenance planning, data archiving, operator assistance, and configuration management. This new approach may also allow for the integration of machinery controls into a total ship control system with seamless support for combat systems. This new shipbo

The Fleet continues to require high performance systems that can operate with dependability in the seas' unforgiving environments and under hostile action. Those demands are not new. What has changed is the urgent priority formerly assigned to national defense issues. The arguments for continued superpower military strength are now roiled in politics along with unsettled budgets and uncertain force level projections. Current expectations revolve about indefinite fiscal and operational issues (difficult funding constraints and broadband threats). In the actual event of ''doing more with less,'' a practical response is to apply the creative power available from sound engineering judgement and the crucible of experience to the immediate needs of the Fleet. The attempt to shorten the path between advanced development effort and Fleet use has been tried occasionally in the past, often, without exemplary results. The Sustainable Hardware and Affordable Readiness Practices (SHARP) program, is a generic R&D effort under OpNav sponsorship that has been working steadily on sensible solutions to product engineering problems. Armed today with fast-time, large-scale computation abilities and modern tools for technical problem solving coupled with specialized engineering knowledge, it has been refreshed and is underway satisfying existing Fleet needs. The relationship between fully responsive engineering services and current operational needs is always demanding. The connection between advanced engineering development (6.3 category funds) and immediate Fleet usage brings added complexity and challenge, both technical and organizational. Illustrative examples of affordable engineering solutions to ''retain, revise, replace or retire'' questions are presented within the context of both Fleet realities and budgetary limitations. The discussion covers legacy system support, civil/military considerations and Fleet maintenance issues. It describes the substantial and critical payoffs i
