The paper describes a digital computer simulation of a class of discrete-time, single-input, stepping extremum control systems with input disturbance and output measurement noise and with an easily instrumented control law. The results of the simulat

This paper arises out of a collaborative project to investigate fishery management, which poses problems of control in the presence of uncertainty, from the point of view of control engineering, which uses dynamic, but not necessarily optimal, feedba

Case studies are reported which show that ideas from stochastic control theory can be exploited to design useful practical controllers. The ideas indicate that the way to design a feedback controller is to implement two separate functions of estimati

The paper investigates adaptive control of discrete-time processes satisfying first-order linear difference equations with random coefficients which may be constant or time-varying. Structural relationships between sub-optimal adaptive control laws a

The paper arises out of a collaborative project to investigate fishery management problems from the point of view of control engineering. A first stage of the investigation was to use software for Computer Aided Design of Control Systems, in the form

The paper concerns recursive state estimation in Wiener systems where the output is a scalar weighted sum of multiple states. A Gaussian approximation to the computed conditional probability distribution for the scalar sum of states is shown to lead

The paper is concerned with the question ‘ when is suboptimal open-loop feedback (OLF) control identical to optimal stochastic control ? ’ A lemma about equivalence between the two controls is formulated and used to obtain sufficient conditions f

Studies of optimal stochastic control problems have drawn attention to three properties: separability, neutrality and certainty equivalence. The relationships between these properties have not yet been fully explored. This paper gives definitions of

In stochastic control the controller generally performs dual functions, reducing uncertainty and exercising control, which can interact. The effect of this interaction on the structure of control laws is investigated by discussing the separability, n
