An adaptive output feedback control algorithm providing exact tuning of adjustable parameters to unknown values, which ensure for the system desired bifurcation properties is proposed. Algorithm is based on passification based adaptive observer design. Several application examples are presented and illustrated by simulation results.

Feedback connection of (strict) passive systems with multiplicative disturbance on the input of one of systems is considered. Series of conditions are proposed, which provide (strict) passivity property for overall system. These conditions enlarge result from Hill, and Moylan (1977), where passivity property of such connection was established. Applications of proposed results to backstepping control and adaptive output control are investigated.

A variety of powerful tools and results in systems and control theory rely on classical Kalman-Yakubovich-Popov-Zames results establishing equivalence between special frequency domain inequalities (FDIs), linear matrix inequalities (LMIs) and time domain inequalities (TDIs). Recent developments have addressed FDIs within (semi)finite frequency ranges to increase flexibility in the system analysis and synthesis. In this paper it is shown that validity of a general FDI within a restricted frequency range is equivalent to validity of the corresponding TDI under rate limitations specified by a matrix-valued integral quadratic constraint. The latter property of a system is termed "restricted dissipativity". Its special cases are "restricted passivity" and "restricted finite gain property". The equivalence between restricted FDI and restricted dissipativity is established for both continuous-time and discrete-time settings. The paper together with the previous developments extends Kalman-Yakubovich-Popov-Zames FDI-LMI-passivity results to FDIs specified within restricted frequency ranges.

Applicability of the proposed results to time-varying chaotic systems is demonstrated by examples of brusselator and Duffing systems. Computer simulation results are presented.

Adaptive control schemes are developed, which provide global asymptotic stability property with respect to state space vector of the plant with functional uncertainty. In the presence of disturbance these schemes ensure boundedness of all trajectories of the system. A switching modification of proposed schemes is considered.

For interval polynomial matrices, we identify the minimal testing set, whose stability can guarantee that of the whole uncertain set. Our results improve the conclusions given by Kamal and Dahleh.

The work deals with universal control formula which provides output global asymptotic stability for affine in control nonlinear system. Development of this result to input-to-output stability (IOS) is also considered....
