摘要:

The relation between non-singularity of the information matrix and local identifiability of the parameters is discussed. For some model structures these two properties arc shown to be equivalent. However, there are also cases where a singular information matrix does not contradict local identifiability.

摘要:

This paper is a sequel to an earlier work in which we applied classical Novnnlinna-Pick interpolation to the stabilization of a single input-output plant, with uncertainly in the gain factor by means of an asymptotically stable control and feedback sensor. In this present work, we show that for the proper design we need a modification of the classical interpolation procedure, a point not clearly brought out in our previous paper.

摘要:

Syntheses of optimal actuators which minimize an energy are considered for oscillatory and non-oscillatory systems with a scalar input from the viewpoint of terminal control with an arbitrary terminal time. Under a certain assumption for the latter systems, hut no assumptions for the former systems, an optimal actuator matrix is shown to be given by the vector directed to the centre of gravity of the convex polyhedron which is constructed by the reciprocal vectors of the eigenvectors of a transition matrix. In the case where the above assumption is not satisfied for the non-oscillatory systems, a sequential approximation method, whose starting point is the vector directed to the centroid of the convex polyhedron, is proposed to obtain a suboptimal solution.

摘要:

A procedure is presented to construct a partial state observer for estimating the linear functions of the state by utilizing the generalized matrix inverse. The method can be applied to linear and bilinear systems.

摘要:

A recent paper by Warwick (1981) discusses the use of state-space models for implementing self-tuning pole-assignment regulators. There are two issues which require further comments.
