    This paper presents an algorithm for minimizing an objective function subject to conventional inequality constraints as well as to inequality constraints of the functional type:max_{omega in Omega} phi(z,omega) leq 0, where Ω is a closed interval inR, andz in R^{n}is the parameter vector to be optimized. The algorithm is motivated by a standard earthquake engi... View full abstract»

    The linear finite-dimensional systemdot{x}(t)=Ax(t) + u(t)cannot, by linear delay feedback controls of the formu(t)= sum min{i = 1}max{m}[B_{i}x(tih) + C_{i}dot{x}(t-ih)], be controlled such thatx(t) equiv 0fortlarge enough. A simple and presumably practical way is proposed of circumventing this limitation of standard delay feedback design. This method c... View full abstract»

    We present the models describing a problem of dynamic file allocation in a network of interacting computers and use dynamic programming to solve for the optimal strategies. The problem is treated for the case when the rates of the file requests are known in advance, as well as when only prior statistics is available for these rates. A separation theorem between estimation of the rates and the opti... View full abstract»

    The problem of designing a static state feedback controller which matches a given multivariable system to a desired ideal system (model) is treated. The system under control is assumed in state space form while the model is assumed in transfer matrix form. An algorithm is developed which separates the conditions which must be satisfied by the system under control and the model to be matched from t... View full abstract»

  • A guaranteed prediction model for complex linear systems

    Publication Year: 1976, Page(s):259 - 263

    The method of approximation in the norm is used to design a linear predictor for the output of a complex linear system at a given future time. It is shown that the computed output is an optimal linear transformation of some variables denoted the "most important" states of the system. The proposed method allows to obtain the system output prediction as a signal belonging to a guaranteed uncertainty... View full abstract»

    Optimal preventive maintenance and repairmen policies for a system of machines subject to degradation with age and intermittent breakdowns and repairs are derived using optimal control theory. When this system of machines forms part of a dynamic process control system, a method of obtaining optimal closed-loop control law is indicated. View full abstract»

    The model reference adaptive system approach together with the positivity lemma for time varying discrete systems are used to construct recursive identifiers with a parallel adjustable model, using adaptation algorithms having a decreasing gain. Identification of single input-single output systems and of multivariable systems is discussed. The identifiers assure an asymptotic unbiased parameter es... View full abstract»

    This paper argues, by means of several examples, that system theory and stochastic control theory are useful and even essential to solve some problems in microeconomics and macroeconomics. It also briefly indicates some potential areas of applications of stochastic control theory to problems in economic theory and regulation of economics. View full abstract»

    Vector Lyapunov functions are used in the stability analysis of large-scale stochastic systems described by Itô differential equations (with stochastic disturbances in the subsystems and in the interconnecting structure). Sufficient conditions for asymptotic stability and exponential stability with probability 1 and in probability are established, in all cases the objective is the same: to an... View full abstract»

  • On a suboptimal control of a hospital inpatient admission system

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (544 KB)

    An open-loop feedback strategy is proposed for the control of the census of a hospital via the inpatient admission system. A semi-Markov population model is used to derive census forecasts. A suboptimal control is obtained by solving at each period a mixed-integer quadratic programming problem. A simulation permits a first evaluation of the proposed strategy as an admission decision rule. View full abstract»

    The relationship between the switching angle and the output torque of a step motor is derived, and the optimal angle, which maximized the output torque, is found. The resulting maximum torque, which varies with the velocity, is an upper limit for the torque that can be generated by the step motor. View full abstract»

    In an estimation problem the statistics of various random processes involved may not be known exactly. Using linear state space modeling techniques, this lack of information can often be represented by allowing certain system model parameters to assume any of a finite set of possible known values with corresponding a priori known probabilities. In this short paper a recursive minimum variance esti... View full abstract»

    This paper considers some aspects of a gradient projection method proposed by Goldstein [1], Levitin and Polyak [3], and more recently, in a less general context, by McCormick [10]. We propose and analyze some convergent step-size rules to be used in conjunction with the method. These rules are similar in spirit to the efficient Armijo rule for the method of steepest descent and under mild assumpt... View full abstract»
