    Shift Walsh matrix is first introduced. Them times mshift Walsh matrix is formed from them times mWalsh matrix by shifting the columns of the Walsh matrix to the right, dropping the lastk(m geq k > O)columns and assigning firstkcolumns of the new matrix as zero elements. Delay Walsh functions can be expanded in terms of Walsh functions using shift Wal... View full abstract»

    This short paper Treats the problem of designing output deadbeat controllers having the property that the control input to the system converges to zero as time goes to infinity, for discrete-time multivariable linear systems. Two configurations of controllers are considered: one is of state feedback; the other is a dynamic controller using an observer. The existence of such controllers is examined... View full abstract»

    We present new methods for computing the greatest common right divisor of polynomial matrices. These methods involve the recently studied generalized Sylvester and generalized Bezoutian resultant matrices, which require no polynomial operations. They can provide a row proper greatest common right divisor, test for coprimeness and calculate dual dynamical indices. The generalized resultant matrices... View full abstract»

    Given an input-output map described by a nonlinear control systemdot{x}=f(x,u)and nonlinear outputy=h(x), we present a simple straightforward means for obtaining a series representation of the outputy(t)in terms of the inputu(t). When the control enters linearly,dot{x} =f(x)+ ug(x), the method yields the existence of a Volterra series represen... View full abstract»

    A stable proper right (left)nth-order inverse of a given linear time-invariant system of orderncan always be constructed, via a simple algorithm, if a proper right (left) inverse exists and the zeros of the given system are stable. Furthermore, it is shown that all of the poles of this inverse can be arbitrarily assigned except those which equal the zeros of the given system. View full abstract»

    In a recent note, it was pointed out that the "ε method" in the application of Routh-Hurwitz criterion fails when the characteristic equation has an arbitrarily small coefficient In this correspondence it is shown that the cause of such a failure is the wrong interpretation of the arbitrariness of ε.

    Two counterexamples are presented in the above correspondence [1] to demonstrate that|A|_{3},the minimum of the standard column-sum norm(|A|_{1})and the row-sum norm(|A|_{2}), is not a valid norm. While these observations are correct, there is an error in [1] in the argument used to justify the use of|A|_{3}as a convergence test. This error is corrected ... View full abstract»

    Formulas for statistics of the standard integral quadratic performance measure used in stochastic linear control system design are derived. The formulas are expressed in terms of dynamical variables under the usual assumptions on noise, plant, and admissibility of control. All of these dynamical variables are expressed as linear transformations of plant state estimates. The practicality of this wo... View full abstract»

    The suboptimal periodic state of a chemical reactor which is unstable under open-loop control is realized and stabilized by applying a simple closed-loop relay control. The method of return state difference in which the computer simulation technique is effectively utilized is developed and used for the stability analysis of the relay control systenm.

    We consider a class of linear dynamical systems with uncertainty in the system matrix, input matrix, input, and state measurement. Based solely on the knowledge of the uncertainty bounds, we give a measured state feedback control that guarantees uniform boundedness and ultimate boundedness in a certain neighborhood of the zero state.

    Scheduling the operation of thermal generating units involves the selection of units to be placed in operation and the allocation of the load among them- These two decisions must be taken so as to minimize the sum of tile startup, banking, and expected riming costs subject to the demand, spinning-reserve, and minimum down-time and up-time constraints and, sometimes, to the following two additional...

    A new design concept for adaptive model-following control systems capable of shaping the error transient responses is developed using the theory of variable structure systems and sliding mode. It is shown that the resulting model-following control system exhibits adaptive properties inherent in adaptive model-following systems designed by existing methods.

  • Elimination of the real positivity condition in the design of parallel MRAS

    All the algorithms developed hitherto in order to obtain a global asymptotically stable "parallel" MRAS (model reference adaptive system) require that a certain transfer function should be made strictly positive real. This condition is restrictive in the case of parallel MRAS used as identifiers or as adaptive state observers, because part of the unknown parameters of the plant to be identified ap...

    A frequency predictor is identified from simulated measurements of power and frequency on a power system. An on-line Ieast-squares algorithm is used along with a new system structure test for model order identification. A comparison of this system structure test with other model order identification tests is also included. The performance of the resultant predictor is then determined as a function...

  • Calculation of Pareto-optimal solutions to multiple-objective problems using threshold-of-acceptability constraints

    A technique is presented for the calculation of Pareto-optimal solutions to a multiple-objective constrained optimization problem by solving a series of single-objective problems. Threshold-of-acceptability constraints are placed on the objective functions at each stage to both limit the area of search and to mathematically guarantee convergence to a Pareto optimum.

    In this paper the design of compensators for output feedback systems which satisfy a sensitivity, reduction criterion is considered for the case when the dynamic compensator is an observer. Using the conditions for comparison sensitivity design of output feedback systems derived by Naeije and Bosgra [4], it is shown that for arbitrary stable state-observers (full or reduced order) there exist feed...

    In this paper the problem of recovering the initial state of time-invariant distributed parabolic systems on the basis of a localized noisy observation is considered, and a criterion for the optimal selection of the measurement point is proposed which takes care of the statistical assumptions about the components of the initial state and of the class of approximating functions describing the spati...
