Designing a qxjasioptimal controlljlaw for one class of dynamic systems

The paper is concerned with determination of optimal control for steady state mode of a dynamic plant. A method is suggested for design of a quasioptimal control law for one class of dynamic systems which are described as sequential connection of a linear static element and a dynamic element where the intermediate signal cannot be measured. The control law is chosen so that the closed loop system is described in the way in which a certain gradient system is which features the desired properties.
