    There is a general class of gyroscopic instruments that use a vibrating member as the sensitive element. Instruments in this class are governed by the differential equationsddot{x} + Omega^{2}x - comegadot{y} = 0ddot{y} + Omega^{2}y - comegadot{x} = 0which describe the position of a reference point on the vibrating member relative to a coordinate system fixed in the instrumen...

    This paper deals with the design of stable adaptive controllers using a model reference approach. A systematic procedure is developed using the concept of positive realness and is generalized to arbitrarily located coutrol parameters. For plants withnpoles and(geq)(n-2)zeros, the uniform asymptotic stability in the large of the adaptive loop is demonstrated. For plants with View full abstract»

    New sufficient conditions for function space controllability and hence feedback stabilizability of linear retarded systems are presented. These conditions were obtained by treating the retarded systems as a special case of an abstract equation in Hilbert spaceR^{n}times L_{2}([- h, 0], R^{n})(denoted asM_{2}). For systems of typecdot{x}(t)=A_{0}x(t)+A_{1}x(t-h)+Bu(t) View full abstract»

    A computationally efficient method for the identification of scalar autoregressive moving average (ARMA) models of the forma(z)y = b(z)u+ c(z)epsilonis introduced; it is called the Cholesky Least Squares (CLS) method. This technique iteratively estimates the coefficients of the polynomialsa(z)andb(z)by using the least squares method on data which, at each iteration... View full abstract»

    A new algorithm, which is an extension of [1, algorithm II], is presented to determine the transmission zeros of the systemdot{x}=Ax+Bu, y=Cx+Dudenoted by(C,A,B,D). The algorithm is based on the observation that for nondegenerate(C,A,B,D)systems, the set of transmission zeros of(C,A,B,D)are contained in the finite eigenvalues of the closed-loop system ma...

    In the above paper a method of realization from input-output sequences is considered. It is pointed out that the method can be used for realizing systems which are not strictly dynamic.S=(A,B,C,D)and the existing methods cannot be applied. It is further claimed that the proposed method is computationally more efficient for the state equation realization from a given transfer function ma... View full abstract»

    The dynamic decoupling problem for a rigid body model of a remote manipulator system is studied. An open-loop decoupling compensator is proposed, which is compatible with the independent-joint-control design philosophy currently adopted in most industrial manipulator systems. Decoupling is achieved by implementing a precompensator at the input to the joint drive system. The feasibility of the deco... View full abstract»

    This paper studies an optimal sensor location problem for a linear distributed parameter system. It is assumed that a criterion for the optimal sensor location is to minimize the trace of the optimal filtering error covariance function. The existence and uniqueness theorem concerning a solution of the optimal filtering error covariance function for the pointwise observation case is considered. The... View full abstract»

    In this paper we consider a multicontroller problem in which each control agent has a different objective function. The actions of the controllers are coordinated by the influence of one controller who plays according to a Stackelberg strategy relative to the remaining players. We investigate this formulation when the information flow is restricted by constraining it to be in the form of sampled d... View full abstract»

    A number of results, involving the notions of controllability (observability) and cyclicity in a linear time-invariant control system, are derived using a new basic theorem. New tests of cyclicity and controllability (observabllity), together with new algorithms to evaluate the controllable (observable) modes and the minimal polynomial are also presented.

    This paper reports an application of LQG theory to the control of three TiO2kilns. Previously derived results on steady-state modeling are used to obtain a set of linear partial differential equations to describe the process. A low-order model is derived by matching the input-output frequency responses. LQG theory is used to determine the sampling period and to justify the selection of ... View full abstract»

    A new technique, which uses a finite orthonormal expansion to approximate input and output functions, is proposed for file identification of a class of nonlinear systems. Walsh functions form the basis of the expansions as a consequence of their useful properties here. That is, the parameter estimation problem is reduced to algebraic form by Fine's relationship for the integral of Walsh functions ... View full abstract»

    A procedure is presented for designing parameter-adaptive control for a single-input, single-output process admitting an essentially unknown but fixed linear model, so that the resulting closed-loop system is globally stable with zero steady-state tracking error between the output of the process and the output of a prespecified linear reference model. The adaptive controller is a differentiator-fr... View full abstract»

    The paper deals with the problem of controlling artificial limbs in cases where several limb functions require control. These situations are of importance, especially to above-elbow upper-extremity amputees. Here, classical EMG (myoelectric) controllers have failed in the past, since they were based on only determining existence or nonexistence of an EMG signal. Recent work by Lyman et al. at UCLA...

    A new method of model reduction is introduced based on the Routh stability criterion. The reduced order transfer function is determined directly from elements in the Routh stability arrays of the high-order denominator and numerator. An eighth order example illustrates the accuracy of the method, the preservation of the frequency response and computational simplicity. The method is equally applica... View full abstract»

    The formulas for the derivatives of state transition matrices [3], [8] are extended in this note. The great usefulness of the matrix calculus [10], [12] is then demonstrated with alternative derivations of results in the theory of sensitivity analysis [8], [14] which are shorter and simpler than the original developments. It is anticipated that the formulas derived herein will be applied to parame... View full abstract»

    An iterative procedure is developed for estimating the domain of attraction of a class of nonlinear systems. The procedure uses an approximation of the system by a Carleman linearization and is suitable for automatic computations. The algorithm is applied to the transient stability problem in electrical power systems and a favorable comparison with previous criteria is obtained. View full abstract»

    A general consistency theorem for stationary nonlinear prediction error estimators is presented. Since this theorem does not require the existence of a parameterized system generating the observations, it applies to the practical problem of modeling complex systems with simple parameterized models. In order to measure the quality of fit between a set of observed processes and a given candidate set... View full abstract»

    This paper presents an application of the self-tuning regulator to the control of a TiO2kiln. The regulator is used in a feedback loop around a kiln already controlled by a discrete regulator designed on minimum-variance principles. The self-tuning regulator has only two parameters. A study of the asymptotic properties shows that the Self-tuning regulator preserves optimality if the min... View full abstract»
