摘要:

The effect of plant parameter variations on systems with nominally time-optimal feedback controllers is investigated. It is assumed that the plant parameter remains constant and that the time-optimal controller calculated for the nominal plant parameter is used. For higher-order systems remarkably small deviations of the plant parameter from its nominal value are found to yield instability. A sub-optimal controller design which results in sliding motion ensures stability and yields acceptable settling time for moderato parameter variations

摘要:

A method is presented here for the solution of a two-person, dynamic, multi-stage cooperative game problem where the two players have only imperfect knowledge of each other's state. For the case where the dynamics of the players is linear, we obtain the optimal control and transmission signal for each of the players. The optimal filters for information gathering are also defined

摘要:

A simple but effective method of divergence control for Kalman filters is described. This is in principle a considerable simplification of the type of divergence control which is based on plant noise estimation.

摘要:

This paper presents an adaptive quantization scheme for the reduction of the percentage error in the output of the quantizer. The improvement in the system performance is illustrated by simulating a uniform step and an adaptive quantizer on a digital computer and comparing their outputs. A significant improvement in the output is achieved by using the suggested scheme.

摘要:

This paper is concerned with the analysis of problems connected with the convergence of optimum seeking procedures, and particularly with the method of planning the rate of convergence and thus influencing the quality of procedures. Local linearization of the relevant dynamic process is performed and quite general results are thus obtained. A solution of multistep algorithms is also presented.

摘要:

This paper is concerned with the deduction of necessary and sufficient conditions under which the minimum-energy, fixed-time, fixed-end point problem has a unique solution for linear systems. A simple method of determining the canonical form of the relevant system is presented.

摘要:

A survey of analysis and synthesis techniques for Kalman-Bucy filtering of systems with parameter uncertainties in the plant matrix and. noise covariance matrices is given. Techniques for analysing the deleterious effects of parameter uncertainties, and testing the system model are presented. The synthesis of estimators for uncertain systems via adaptive estimation, bounding techniques, and multiple performance criteria is discussed.

摘要:

An attempt is made here to demonstrate the usefulness of quasilinearization technique for the estimation of states and parameters of a discrete-time system. The estimation problem is viewed as a least-squared-errors problem which is then transformed into a Two Point Boundary Value (TPBV) problem by the use of the Discrete Maximum Principle. The TPBV problem is then solved by the quasilinearization technique.
