摘要:

The transcendental equation relating the parameters of a closed trajectory of a relay system containing a symmetrical two-position element, a dead element and a rational part of the second order has two solutions. It will be shown that only one of these solutions supplies the self-oscillation of the system.

摘要:

A sufficient condition for local stability of the spatially discretized model of a class of non-linear distributed parameter systems is derived using the circle criterion for stability and bounded-input, bounded-output stability. As a physical system the catalytic packed-bed tubular reactor is taken to illustrate the application of the theorem to process control systems. The stability condition in the large derived from non-linear system equations is compared with the stability condition in the small derived from linearized system equations. Interpretations of the result are given in terms of physical variables.

摘要:

The purpose of this paper is to present some detailed results which enable the solution of a systom equation by means of transforms instead of the convolution integral. Some common control forces are studied and the results summarized. Application of several control forces and delayed control forces are included in this study.
