    This paper deals with further advances of the author's recent work on optimal design of control systems and Wiener filters. Specifically, we consider the problem of designing a system to control a plant when (1) not all state variables are measurable, (2) the measured state variables are contaminated with noise, and (3) there are random disturbances. An explicit design procedure (well adapted to d... View full abstract»

    The mathematical analysis of linear dynamic systems, based on experimental test results, often requires that the frequency response of the system be fitted by an algebraic expression. The form in which this expression is usually desired is that of a ratio of two frequency-dependent polynomials. In this paper, a method of evaluation of the polynomial coefficients is presented. It is based on the mi... View full abstract»

    In many multi-stage decision processes we face the problem of dealing with random variables whoe distributions are initially imperfectly known, but which become known with increasing accuracy as the process continues. In this paper we shall show how Dynamic Programming may be used to treat a class of such problems, which are currently called adaptive processes. After discussing the general theory,...

    This paper is concerned with obtaining the optimum system in the Weiner sense for the multipole system. Earlier literature has shown how to obtain the mean-square value of the error when the multipole system transfer function has been specified, but thus far no published work has shown how to solve the synthesis problem, in general, for this case. The principal reason that this problem has appeare... View full abstract»

    The subject of this paper is the analysis of periodically switched electric networks. A method for determining a sampled-data system which is equivalent to a given member of a class of periodically switched electric networks is first presented. A technique for determining the response of the system to a given input function is then discussed in detail. Next it is shown that it is possible to ident... View full abstract»

    An attempt is made in the subject paper to evolve a basic philosophy for adaptive control systems. A method is described for determining the system impulse response from measurements of instantaneous system input and output. The impulse response is expanded in a Taylor series, to facilitate solution of the convolution integral. From a knowledge of the impulse response and the system error, the nec... View full abstract»

    In many engineering, economic, biological, and statistical control processes, a decision-making device is called upon to perform tinder various conditions of uncertainty regarding underlying physical processes. These conditions range from complete knowledge to total ignorance. As the process unfolds, additional information may become available to the controlling element, which then has the possibi...
