    This note is concerned with the stabilization of uncertain systems via output feedback. The principal result demonstrates that if an uncertain system can be stabilized via linear static state feedback, then one can stabilize uncertain systems via observer-based feedback which are "arbitrarily close" to the original system. Most importantly, these results are achieved under relatively weak assumpti... View full abstract»

    In the above paper an optimal control problem with discounting was proposed to achieve closed-loop mode stabilization for linear systems with jump parameters. The paper used the unstated hypothesis that the diagonal entries of the generator of the jump process are equal. This correspondence discusses the situation in the general case. View full abstract»

    This note is concerned with piecewise constant controls. In order to supplement the above-mentioned paper sufficient conditions for the existence of a piecewise constant control are provided. Moreover, although for an n -dimensional control system the switching times for the piecewise constant control cannot he chosen arbitrarily, it is shown that the switching... View full abstract»

    In an earlier paper, the author proposed an iterative method for generalized complementarity problems with Lipschitz continuous and strongly monotone functions. Here we show that a slightly modified method can be developed to solve a generalized complementarity problem with a Lipschitz continuous, pseudomonotone, and integrable function. View full abstract»

  • A computational algorithm for pole assignment of linear multiinput systems

    An efficient computational algorithm for pole assignment of linear multiinput systems is proposed. A preliminary stage of the algorithm is a reduction of the system matrices into orthogonal canonical form. The gain matrix elements are then found by orthogonal transformation of the closed-loop system matrix into upper quasi-triangular form whose diagonal blocks correspond to the desired poles. The ...

    Performance and stability behavior of discrete adaptive systems in the presence of fast parasitics are examined. When the parasitics are locally bounded, it is shown that sufficiently general input sequences yield a bounded response within a closed region. In the general case, it is established that a region of attraction exists from which all sequences converge to a target set which contains the ... View full abstract»

  • An adaptation algorithm for parallel model reference adaptive bilinear systems

    An adaptation algorithm is presented for parallel model reference adaptive bilinear systems. The output error converges asymptotically to zero and the parameter estimates are bounded for stable reference models. The convergence criterion depends only upon the input sequence and a priori estimates of the maximum parameter values. A passivity condition, which is generally difficult to verify, is not...

  • The parallel implementation of a cascade adaptive identification algorithm

    This note presents a new method of parameter estimation, called cascading, for use in adaptive control. The algorithm is shown to be superior to a simple recursive least-squares estimator especially for a system characterized by noisy measurements. The algorithm can be implemented easily on a parallel processor such as ORAC [1], [2] or any sequential processor. When the algorithm is implemented on... View full abstract»

    Control system response possibilities for a finite-dimensional, linear, time-invariant plant are governed by an interaction between the possible plant transfer function inverses, when they exist, and the closed-loop response maps themselves. Possible minimal state spaces for such inverses are comprised algebraically of a space of plant zeros and a variable space of poles, with the latter having a ... View full abstract»

  • An improvement on Routh approximation technique

    A modification of the Routh approximant is introduced which results in a considerable improvement over the conventional Routh approximation technique. Since some amount of arbitrariness is available in the time moment expressions of the conventional Routh approximant, it can be utilized to minimize the step response error while preserving the stability and moment matching property of the conventio...

  • An asymptotically efficient ARMA estimator based on sample covariances

    An asymptotically efficient autoregressive moving-average (ARMA) spectral estimator is presented, based on the sample covariances of observed time series. The estimate of the autoregressive (AR) part is shown to be identical to the optimal instrumental variable (IV) estimator in [7] although derived here using a different approach. The moving-average (MA) spectral parameter estimate is new. View full abstract»

    This paper proposes a new direct adaptive control algorithm which is robust with respect to additive and multiplicative plant unmodeled dynamics. The algorithm is designed based on the reduced-order plant, which is assumed to be minimum phase and of known order and relative degree, but is analyzed with respect to the overall plant which, due to the unmodeled dynamics, may be nonminimum phase and o...

    In this note the concept of zero for linear discrete-time SISO periodic systems is discussed. The definition is based on a time-invariant MIMO equivalent representation. An input-output characterization of the zeros is provided which extends a well-known property for time-invariant systems. View full abstract»

  • A sufficient condition of output feedback stabilization of uncertain systems

    A sufficient condition is derived for the existence of an output constant gain feedback controller which stabilizes a single-input single-output dynamical system with a linear nominal part and matched uncertainties. The sufficient condition is significantly less restrictive than a recently derived one [1]. If such a controller exists, it may readily be computed. View full abstract»

  • Dynamic path planning for a mobile automaton with limited information on the environment

    The problem of path planning is studied for the case of a mobile robot moving in an environment filled with obstacles whose shape and positions are not known. Under the accepted model, the automaton knows its own and the target coordinates, and has a "sensory" feedback which provides it with local information on its immediate surroundings. Ibis information is shown to be sufficient to guarantee re... View full abstract»

    The role of feedback control in the solution of aircraft stability and control problems is discussed. It is argued that this role is becoming more and more important and is a key to meeting performance objectives for new aircraft. As a consequence, the control engineer must develop control laws for applications with many, sometimes conflicting, control objectives and stringent safely requirements.... View full abstract»

    This paper examines some of the consequences of finite word lengths in digital control. It is shown that, in many cases of practical importance, the usual shift operator formulation is inferior to an alternative formulation which we designate the delta operator approach. This latter approach is shown to give better coefficient representation and less roundoff noise in many cases. We thus argue tha... View full abstract»
