    This paper starts with a straightforward self-contained treatment of the generalized Nyquist stability criterion based on the eigenloci of the open-loop transfer function matrix. The derivation is straightforward and does not invoke algebraic function theory, branch cuts, and Riemann surfaces. A similar criterion is derived for the distributed case where the open-loop transfer function matrices be... View full abstract»

    Scholars have discussedC^{infty}input-output systems in a number of settings. Recent work of Hirschorn's has given sufficient conditions for local invertibility of systems with multivariable inputs. Here we give another such condition which appears to be independent of Hirschorn's. View full abstract»

    This paper considers the problem of matching the transfer function matrix of a given two-dimensional system to that of a desired two-dimensional model using output feedback. The approach followed is essentially based on the idea of equating the coefficients of the likew^{i}z^{j}terms in the relationshipT_{c}(w,z)= T_{m}(w,z)whereT_{c}(w,z)is the closed-loop transfe...

    The feedback control which achieves minimum-time transition to the state origin for nonoscillatory second-order plants with scalar saturable input involves a function of state raised to a power α which corresponds to the ratio of the plant eigenvalues. The feedback system is found to be acutely sensitive to variations in the parameter α, viz., the state origin cannot be reached in finite... View full abstract»

    This paper considers observers of slow states in singularly perturbed systems. Upper bounds are derived on observer error due to use of a reduced-order model in the observer. This error is shown to be 0(μ), where the singular perturbation parameter μ is a measure of the separation between the slow and fast eigenvalues of the full-order system. View full abstract»

    Predictive guidance equations for systems with time delays are developed using optimal control theory to obtain interceptor steering gains. The time response of the interceptor is approximated by a linear first-order time lag, and the optimal steering gain is evaluated using a quadratic penalty function. The optimal control for interception is determined to be a linear function of the predicted po... View full abstract»

    The Routh-Hurwitz reduction method is shown to have a serious disadvantage in that the reduced model may approximate the nondominant poles of the system and hence lead to erroneous approximations. A numerical example is given to compare the Routh-Hurwitz method to the Padé approximation method. View full abstract»

    Feedback controls based on the receding horizon method have proven to be a useful and easy tool in stabilizing linear ordinary differential systems. In this paper the receding horizon method is applied to linear systems with delay in the control. An open-loop optimal control which minimizes control energy subject to certain side constraints is first derived and then transformed to a closed-loop co... View full abstract»

    It is shown that continuous-kernel nonzero-sum games with compact strategy spaces could admit both pure and mixed Stackelberg equilibrium solutions, if the cost function of each player is either nonquadratic or nonconvex in his own decision variable. In such a case, the mixed Stackelberg strategy will yield a lower average cost for the leader than the pure Stackelberg strategy. It is also verified... View full abstract»

    Sufficient conditions for global and local controllability of certain types of nonlinear time-varying systems with implicit derivative are given. The results are obtained by using the notion of measure of noncompactness of a set and the Darbo fixed-point theorem. View full abstract»

    A well-known method for estimation of parameters in linear systems with correlated noise is the extended Kalman filter where the unknown parameters are estimated as a part of an enlarged state vector. To avoid the computational burden in determining the state estimates when only the parameter estimates are required, a new simple form of the extended Kalman filter, where the state consists only of ...

    We give some fairly general circumstances under which the experimental design problem for linear dynamic systems with correlated noise can be put in the exact form of the Kiefer-Wolfowitz experimental design problem. Optimal inputs are characterized in terms of their spectral measures with respect to a resolution of the identity in a certain reproducing kernel Hilbert space. Numerical methods esta...

    The purpose of this paper is to resolve the control problem of shearing a rolled billet. The appropriate control should result in shearing each section to a length which consists of a predetermined basic length and a tolerance. The control should be effected with the minimum waste criterion. Because the final length of the rolled billet to be cut is not known, the control is based on the predictio... View full abstract»
