    A new formulation of the differential matrix Riccati equation is presented and a closed analytical solution is obtained under the hypothesis that certain commutativity conditions are fulfilled on a transformed space. The formulation generalizes the results of [1] on algebraic equations to differential matrix Riccati equations. To illustrate the usefulness of the method, a closed analytical solutio...

    This note considers the problem of stabilizing a linear dynamical system (Σ) whose state equation includes a time-varying uncertain parameter vectorq(cdot). Given the dynamicsdot{x}(t)=A(q(t))x(t)+ B(q(t))u(t)and a bounding setQfor the valuesq(t), the objective is to choose a control lawu(t)=p(x(t))guaranteeing uniform asymptotic stabilit...

    The aim of this paper is to point out that a sufficient condition in the existence theorem of the solution of Riccati equations obtained in the above paper is also necessary. Our proof of the theorem inclusive of the sufficiency is more perspicuous although it is the same in essence as that in the above paper. View full abstract»

    Asymptotically stabilizing feedback controls for a class of bilinear systems are discussed; a simple modification which strengthens a result of Slemrod [1] is noted and illustrated by example. View full abstract»

    This note presents results relating to the adaptive control of linear time invariant systems having purely deterministic disturbances such as sine waves, biases, etc. Two key points are made. First, it is shown that the usual ARMA model used in adaptive control can also include a description of purely deterministic disturbances. Second, it is shown that the existing convergence theory for adaptive... View full abstract»

    This note presents some new time update formulas for certain types of lattice algorithms used in autoregressive modeling of stationary time series. The new formulas enable the computation of the autoregressive coefficients in a number of operations per time step proportional to the model order. View full abstract»

    Some recently developed algebraic theorems of λ-matrices and applications to matrix fraction descriptions of a class of multivariable systems are introduced. Also, a new block-pole placement is developed for the state-feedback block decomposition of multivariable systems. View full abstract»

  • Linear feedback decoupling--Transfer function analysis

    The problem of linear system decoupling is examined based on recent results on linear feedback. New insight is obtained, through which resolution of the decoupliug problem is accomplished by calculations, performed directly on the given transfer matrix. Computation of the decoupling compensators follows by easy constructions. The problem of feedback block decoupling with internal stability, is als... View full abstract»

  • Optimal strategies for families of alternative bandit processes

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (456 KB)

    Many stochastic resource allocation problems may be formulated as families of alternative bandit processes. One example is the classical one-armed bandit problem recently studied by Kumar and Seidman. Optimal strategies for such problems are known to be determined by a collection of dynamic allocation indexes (DAI's). The aim of this note is to bring this important result to the attention of contr... View full abstract»

  • Global adaptive pole placement: Detailed analysis of a first-order system

    This paper studies a deterministic adaptive pole positioning problem for a linear first-order system. The principal contribution is to specify an adaptive control law which secures global convergence. The key conditions required are that an externally available plant input be persistently exciting, and that an underbound (not necessarily tight) be known on the magnitude of the input coupling gain....

    A "uniformly balanced" realization for linear time-variable systems is defined. This representation is characterized by the fact that its controllability, and observability Gramians are equal and diagonal. Existence and uniqueness of the uniformly balanced realization is studied. Such a framework has many remarkable properties and leads to a novel method for approximating time-variable systems, wh...

    The class of analytic time-varying linear systems is considered. Different balanced realizations of such systems are defined, and their existence and properties are analyzed. The results are then used to derive reduced order approximations (also for unstable systems). A method is suggested to determine the order of a "good" approximation. View full abstract»
