摘要:

This paper describes a breadboard system fabricated to study the control of a solar mirror. The appropriate Euler equations were used to simulate the dynamics on an analogue computer. The accuracy of the computer study was checked with actual performance data.

摘要:

This paper considers an aspect of the problem of representing the process of self-organization by a feedback control process. In particular, the problem is considered where the desired objective of the self-organizing system can be attained only by first setting up certain intermediate sub-goals. These sub-goals are continually adjusted by giving them varying weighting factors. Here, the problem of determining these weighting factors is considered. The approach is by the use of contraction mapping as a method of representing a feedback control process.

摘要:

Systems containing two non-linearities separated by a stabilizing network of the formSand (1 + τS) are considered. The input to the second non-linear block is not a pure sinusoid but contains all higher harmonics. An equivalent non-linear characteristic is found which changes with frequency and amplitude, and a joint describing function is obtained. The method is believed to be novel and is applicable even if one non-linearity is of the backlash type.

摘要:

The demodulating compensator, of fairly recent origin, is quite useful in carrier control systems, especially because of its near immunity from the carrier frequency drift effects and its small sire, weight, cost, etc.

摘要:

The present paper is the sequel to a previous paper by the author. The main purpose of the present paper is to justify the claim made curlier that the approach to stochastic optimal control previously employed can be extended to the case of noisy observations of the state.

摘要:

In this paper are presented methods for testing the connectedness of a finite graph and for the determination of all the trees of the same. While the tests for the connectedness furnished in this paper are stated in terms of the concopt of edge matrix, a concept introduced in the paper, the process of finding all the trees of a finite N-graph G, makes use of the cover table, which expresses the cover conditions of all the vertices of the graph G by its edges. From the cover table of G, the φGset of somo suitable partial graphs with (n — 1) edges of G is determined. Then, from the members of φGare chosen either those which are connected or those which contain no cycle and in either case the set TrGof all the trees of G is obtained. The method of finding the members of the set φGis however iterative and in this process no duplication of results occurs.
