    This book offers a stimulating introduction to linear control theory with an H-optimality criterion. The general problem dealt with in the book, called the ??standard problem,?? consists of designing a controller which minimizes the H,-norm of a tixed closed-loop transfer matrix. The H norm of a transfer matrix is the maximum over all frequencies of its larg... View full abstract»

    A class of multipliers that can be used for producing alternative stability tests for systems having a single incrementally conic nonlinearity f(x) has been nearly parameterized by Zames and Falb [1]. The present note demonstrates how linear programming can be used to compute optimal multipliers leading to a frequency domain stability criterion that is less c... View full abstract»

  • Optimal sensor location for detecting changes in dynamical behavior

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (792 KB)

    We address the problem of optimal sensor location for monitoring the eigenstructure of a multivariable dynamical system. The criterions which are optimized are the power of new tests designed for detecting and diagnosing changes in the eigencharacteristics of a system [3], [12]. The key points are the choice of the parameterization for computing the criterion and the comparison of designs with a d... View full abstract»

    In this note we investigate systems which combine the timing requirements of real-time processing with the complexity of knowledge processing. In such real-time environments it cannot be guaranteed that all processes meet their deadlines but it is possible to isolate a subset of critical processes which must meet their deadlines. We call such systems semi-hard real-time control systems. Although p... View full abstract»

  • Robust trajectory planning for robotic manipulators under payload uncertainties

    Publication Year: 1987, Page(s):1044 - 1054
    Cited by:  Papers (17)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (944 KB)

    A number of trajectory planning algorithms are available for determining the joint torques, positions, and velocities required to move a manipulator along a given geometric path in minimum time. These schemes require knowledge of the robot's dynamics, which in turn depend upon the characteristics of the payload which the robot is carrying. In practice, the dynamic properties of the payload will no... View full abstract»

  • Periodic tracking adaptive control for multivariable systems having more outputs than inputs

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (352 KB)

    This note presents an adaptive control algorithm for multivariable systems in which the number of outputs is greater than the number of inputs. The algorithm can force the outputs to track arbitrary given reference signals periodically. This is the best tracking performance for systems lacking output function controllability. It has been shown that the tracking period is the upper bound on the con... View full abstract»

  • The optimal projection equations for static and dynamic output feedback: The singular case

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB)

    Oblique projections have been shown to arise naturally in both static and dynamic optimal design problems. For static controllers an oblique projection was inherent in the early work of Levine and Athans, while for dynamic controllers an oblique projection was developed by Hyland and Bernstein. This note is motivated by the following natural question: What is the relationship between the oblique p... View full abstract»

    We investigate the theoretical properties of new instruments-based test statistics recently proposed [3] for detection and diagnosis of changes in the AR part of a multivariable ARMA process. The design flexibilities are analyzed, and the optimum design of the test is exhibited. The connection with the accuracy of the I.V. identification method [14] is established, and the comparison with the loca... View full abstract»

    The need to equip robotic systems with a high degree of dexterity and adaptability to a wide range of precise manipulation tusks has given rise to increasing interest in the utilization of various sensing modalities, including force and tactile sensing. In this paper a general framework is proposed for incorporating both a priori task geometry information and on-line observations, including force ... View full abstract»

    Square-root information falter formulations of the discrete-time Kalman filter are sometimes thought to be restricted by a requirement that the state transition matrix be nonsingular. In a recent publication [1], Boncelet, Jr. and Dickinson have shown that this restriction is not necessary. For problems where both formulations can be applied, the generalized formulation is, however, more computati... View full abstract»

    A class of discrete second-order random processes, described by linear time-invariant state-space models, is investigated. Equivalent realizations with reduced number of noise inputs are presented. In contrast to the innovations approach these realizations have time-invariant parameters. View full abstract»

    The coefficients of the optimal steady-state k -step ahead predictor for a scalar ARMAX process in general depend on k . It is shown that a simple formula completely characterizes all these coefficients. This extends previous results on the characterization of ARMA predictors. View full abstract»

  • Directional interpolation approach to H-Optimization and robust stabilization

    It is shown that, under a mild condition, H\infty -optimization and robust stabilization are equivalent to a directional interpolation problem which is a matrix extension of the classical Pick-Nevanlinna interpolation problem. A classical iterative method, which is an extension of the Schur-Nevanlinna algorithm, is given for solving the problem. This method d... View full abstract»

  • On adaptive control of stochastic bilinear systems

    The minimum variance control law for bilinear systems with known parameters is shown to yield in most cases controls with infinite variance; this calls into question the use of the so-called bilinear self-tuning regulators. An adaptive weighted minimum variance controller based upon the cost with weighted control efforts is suggested for first-order bilinear systems and is shown to yield boundedne...

    Introducing a cost term on the highest power of the nonlinear polynomial, we derive a simple direct adaptive control weighted suboptimal control algorithm which is very useful for the control of all stable nonminimum-phase and some unstable nonminimum-phase linear systems having a polynomial input. Both stochastic and deterministic situations are considered and the global convergence of the propos... View full abstract»

    Jump linear systems are considered in a random environment where they are subject to additive and multiplicative noises. Stochastic notions of stabilizability and detectability are introduced to characterize the asymptotic behavior of the optimal jump linear quadratic Gaussian regulator and a dual Kalman filter.

    Transient signals between parameter updating can be used to generate internal persistency of excitation (PE) conditions in adaptive control problems. In particular, this fact can be advantageous in indirect adaptive control in order to prevent the estimated plant from converging to nonstabilizable models. View full abstract»
