AUTOMATIC CONTROL SYSTEMS WITH VARIABLE STRUCTURE,
Abstract
The book examines principles of construction of one class of nonlinear automatic control systems - systems with variable structure. Basic attention is allotted to different problems of control of linear objects with constant and variable parameters both for free and for forced motions. It is shown that the principle of changeability of structure permits ensuring high-quality control of free motion of an object, and in the case of change of parameters in a wide range permits constructing a system insensitive to these changes. Methods of synthesis of control for objects working under conditions of continuously acting external perturbing forces are given. It is shown that for a broad class of disturbances it is possible to ensure independence of quality indicators of the control process by using executing devices with variable structure. A very important peculiarity of the examined class of systems from the practical point of view is that for realization of offered laws of control required is information neither about the value of variable parameters of the object nor on disturbances applied to it. The offered methods of control of objects with one adjustable value are generalized in case of multiconnected objects with several adjustable coordinates. (Author)
