摘要:

In this paper the suboptimality of the computer control approach in the linear quadratic problem is studied. When a digital computer controller is used, a hybrid linear control system is obtained. The parameters of this system can be chosen in different ways which all lead to suboptimal controllers. The case when a digital computer implemented observer is used was also studied and a generalization of the earlier results of Bongiorno and Youla was obtained.

摘要:

A simplex algorithm for solving the minimum fuel problem for linear discrete control systems is described. In this algorithm an initial basic feasible solution is available with no artificial variables needed. Also minimum computer storage is required. The algorithm is a simple and fast one. A numerical example is given

摘要:

This paper presents a new stable scheme for the discrete adaptive observer based on Popov's hyperstability theorem. Our adaptive observer enables us to simultaneously estimate the unknown parameters and the inaccessible state variables of the single-input single-output linear plant expressed in the discrete type of observable canonical form, using only input-output. measurements. Our scheme can be easily implemented on a digital computer with simple algorithm. The effectiveness of the proposed scheme is demonstrated by the computer simulation carried out for a second-order plant.
