Next Generation Air Traac Management will allow for the possibility of free ight, in which each aircraft chooses its own optimal route, altitude and speed. In a free ight environment, the trajectories of several aircraft may be connicting, in which case aircraft may or may not cooperate in resolving the connict. This paper presents a method for noncooperative connict resolution in which each ai...

Abstract: Methods from learning theory are used in the state space of linear dynamical and control systems in order to estimate the system matrices. An application to stabilization via algebraic Riccati equations is included. The approach is illustrated via a series of numerical examples.

This paper presents a general matrix algorithm for analysis and synthesis of digital filters. A useful method for computing the state-space matrix of a general digital network and a new technique for the design of digital filters are shown by means of examples. The method proposed in this paper allows the analysis of the digital filters and the construction of new equivalent structures of the c...

This study presents a new finite element approximation for an optimal control problem (P ) governed by the heat equation and with end-point state constraints. The state constraint set S is assumed to have an empty interior in the state space. We begin with building a new penalty functional where the penalty parameter is an algebraic combination of the mesh size and the time step. Based on it, w...

The experimental performance of recently proposed approximation techniques for nonlinear optimal, and nonlinear H 1 control compare favorably with other popular design techniques including LQR, linear H 1 , backstepping, and passivity based control. The performance of the aforementioned six control laws on a physical system similar to the Nonlinear Benchmark problem proposed by Bernstein is com...

This note presents a method for the reduction of controller fragility. The method is based on the sensitivity of closed-loop poles to perturbations in the controller parameters. By means of a state space parameterization of the controller, the closed-loop pole sensitivity can be reduced. A controller fragility measure based on the closed-loop pole sensitivity is proposed. Conditions for the opt...

We illustrate an algorithm that starting from the image representation of a strictly bounded-real system computes a minimal balanced state variable, from which a minimal balanced state realization is readily obtained. The algorithm stems from an iterative procedure to compute a storage function, based on a technique to solve a generalization of the Nevanlinna interpolation problem.

Software projects are required to be tracked during their execution for controlling them. According to state space approach, the tracking problem leads us to have a project state transition model and project status model. A key factor in modeling software projects is to model the project with uncertainty involved in the parameters related to project state transition model and project status mod...

a wind farm is a collection of wind turbines built in an area to provide electricity. wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. in this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in hl1 level is proposed. in proposed procedure, application of fuzzy – markov f...
