摘要:

AbstractA model for a viscoelastic coating is derived and the coating reflectivity is determined. A coating which minimizes the reflection of sound waves is partly bang‐bang and partly singular. A new gradient type algorithm is presented for computing the optimal control. Formulae for the gradient of the cost in optimal control are derived in various setting

摘要:

AbstractThis paper develops an optimal control model for the firm's decision‐making concerning pollution control spending, employment and investment. The model explicitly considers the impact of adjustment costs of changing the level of the pollution stock and involves three state variables and two control variables. Necessary conditions are derived by the maximum principle. The results include an optimal employment‐investment‐pollution abatement programme, an optimal pollution control decision rule, the equilibrium optimal pollution control and spending plan, and the equilibrium employment‐investment d

摘要:

AbstractA simple parameter adaptive controller design methodology is introduced in which steady‐state servo tracking properties provide the major control objective. This is achieved without cancellation of process zeros and hence the underlying design can be applied to non‐minimum phase systems. As with other self‐tuning algorithms, the design (user specified) polynomials of the proposed algorithm define the performance capabilities of the resulting controller. However, with the appropriate definition of these polynomials, the synthesis technique can be shown to admit different adaptive control strategies, e.g. self‐tuning PID and self‐tuning pole‐placement controllers. The algorithm can therefore be thought of as an embodiment of other self‐tuning design techniques. The performances of some of the resulting controllers are illustrated using simulation examples and the on‐line application to an experim

摘要:

AbstractIn this paper we analyse a model which describes one section of an Alpine climbing tour. As a control variable, we introduce the intensity of belaying. The objective of control is the maximization of the safety or pleasure of climbing. We focus our attention on the qualitative structure of the optimal belaying strategy and on the question of how it depends on the degree of climbing difficulty. The model is based on a stochastic approach; its solution, however, is derived by means of deterministic control theory.

摘要:

AbstractThe linear quadratic Gaussian (LQG) optimal control problem of single‐input‐single‐output (SISO) analogue and digital systems can be solved using Wiener‐Hopf techniques of spectral and partial factorization. A new form of the Wiener‐Hopf result is derived, followed by a description of how the solution is implemented in Program CC, a user‐friendly, command driven, computer‐aided‐control‐system‐des

摘要:

AbstractPolynomial Diophantine equations can be used to solve pole‐placement problems and linear quadratic Gaussian (LQG) optimal control problems, for both analogue and digital single‐input‐single‐output (SISO) systems. A description is presented of the how these algorithms are implemented in Program CC, a user‐friendly, command driven, computer‐aided‐control‐system‐desig
