Circle and Popov Criterion for Output Feedback Stabilization of Uncertain Systems
In this paper, we address the problem of output feedback stabilization for a class of uncertain dynamical systems. An asymptotically stabilizing controller is proposed under the assumption that the nominal system is absolutely stable.

It is well known that all real automatic control systems (ACS) are significantly nonlinear systems. Along with this, in engineering analysis the simplifications of their mathematic description, that is, linearization, are inevitable.

Adhesive Boundary Element Method Using Virtual Crack Closure Technique
In this study, a new adhesive contact model is built upon a boundary element method (BEM) model developed by Pohrt and Popov (2015). The strain energy release rate (SERR) on the edge of the bonding interface is evaluated using Virtual Crack Closure ...

DESCRIPTION OF A NONLINEAR LINK IN A CONTROL SYSTEM WITH DISTRIBUTED PARAMETERS
The problem of adequate representation of models of real objects in the form of systems of linear equations is shown. As a solution, a method of analysis and synthesis of this class of systems with a single nonlinear element is proposed. At the same time,

Actuator Saturation Compensation for Fast Tool Servo Systems With Time Delays
Fast tool servo systems with high precision and high speed pose significant challenges to servo control at the nano-scale. The saturation of the control actions, time delays and system uncertainties further complicate the control challenges.

Longitudinal Absolute Stability of a BWB Aircraft-Pilot System with Saturated Actuator Model [PDF]
This paper deals with the analysis of the P(ilot) I(n-the-Loop) O(scillations) of the second category (with rate and position liming in the closed loop pilot-vehicle system), caused by the dynamic coupling between the human pilot and the aircraft.

A generalization of the Popov criterion [PDF]
Abstract A criterion for the stability of control systems which contain an arbitrary finite number of memoryless nonlinearities is considered. The criterion is such that the degree of stability may be specified, and such that for the case when the absolute stability of a control system having one memoryless nonlinearity is considered, it reduces to ...

Absolute stability for the lateral-directional BWB model with rate limited actuator [PDF]
In this paper the authors present a study regarding the interaction between the human pilot and the aircraft which may result in a dangerous phenomenon called Pilot Induced Oscillations (PIO), in the context of the lateral directional motion.
