This paper deals with the observer design of nonlinear tubular chemical reactor models. The analysis is performed on a linearized version of the model around a steady-state profile, in which some coefficients are a function of the spatial variable. The study starts from a general model of chemical tubular reactors that will serve as a benchmark model for the formulation in the infinite dimensional Hilbert state space. The optimal output injection operator associated to the proposed observer is computed via the solution of the infinite-dimensional Riccati equation in the space variable. The performance of the observer is illustrated through numerical experiments of an industrial pulp bleaching tubular reactor model.
This paper is concerned with the observer design for one-dimensional class of nonisothermal tubular reactors considering in-domain pointwise measurements of temperature over the entire spatial domain. A Lyapunov-based...

This paper is concerned with the observer design for one-dimensional class of nonisothermal tubular reactors considering in-domain pointwise measurements of temperature over the entire spatial domain. A Lyapunov-based design method is derived for the PDE system providing sufficient conditions, in the form of standard linear matrix inequalities (LMIs), for the exponential convergence of the estimation error with a given decay rate. The approach is applied and tested with a representative case of a tubular reactor with non-monotonic kinetics satisfying the sufficient solvability conditions. Simulation results support the effectiveness of the suggested design.

Optimal Arrival Time Scheduling (OATS) is a strategy for intersection control in an environment of highly or fully automated vehicles previously developed by the authors. It schedules vehicle arrivals at the intersection with a Mixed Integer Linear program (MILP). OATS goal is to minimize vehicle delay at the intersection and its approaches while avoiding collisions. This goal is achieved by decomposing the coordination problem into the aforementioned MILP and three other subproblems. In this work, we extend the OATS strategy allowing for the modeling of any intersection layout and arbitrary speed profiles inside the intersection. Simulation results confirm that the strategy is able to perform adequately in realistic traffic intersections.

Developmental tests have been conducted in the Fleet to demonstrate concepts for reducing man—hoars required to perform certain shipboard functions while maintaining or improving effectiveness. Experiences during the Preparation, Conduct, and Reporting of the tests are described including the CNO Pilot program for Reduced Bridge Manning; Integrated Bridge System (IBS); Facilities Maintenance (housekeeping); Wireless Communications During Damage Control Evolutions; and the Ship Contrblman. Areas discussed include system design and interface requirements; elements that go into tests designed for shipboard evaluation; approval requirements to conduct such tests; how to get Fleet Support in terms of personnel and assets; logistics and training requirements; and finally, what Fleet testing buys that other means do not.
