Brief paper: Analysis of feedback-loop interactions with actuator and sensor parasitics
K.D. Young,Petar V. Kokotovic +1 more
TL;DR: In this article, the authors employ singular perturbations to model and analyze the interaction of sensor-actuator dynamics with the fast modes created by high feedback gain, which is of practical importance to investigate the effects of such "parasitics".
Journal ArticleDOI
Stability analysis of an adaptive system with unmodelled dynamics
B. Riedle,Petar V. Kokotovic +1 more
TL;DR: In this article, the authors derived stability bounds for a simple adaptive system with one unmodelled (parasitic) pole which is approximated by a right half-plane zero, and showed that a plant bypass ensures a global stability property by making the linear time-invariant part of the adaptive loop strictly positive real (SPR).
Proceedings ArticleDOI
Robust integral control for a class of uncertain nonlinear systems
TL;DR: For a class of systems with uncertain nonlinearities, the authors design robust integral controllers which achieve the tracking of constant reference signals which are of lower order than adaptive controllers would be were parameterizations of the uncertainties available.
Proceedings ArticleDOI
Tools and procedures for robust control of nonlinear systems
TL;DR: Using the concept of a robust control Lyapunov function, robust backstepping tools are presented and it is demonstrated how they can be used in systematic design procedures.
Journal ArticleDOI
A scaled feedback stabilization of power integrator triangular systems
D.B. Dacic,Petar V. Kokotovic +1 more
TL;DR: A dynamic version of unbounded time-varying scaling of the states for feedback laws for power integrator triangular systems which globally asymptotically stabilize (GAS) the origin despite the uncontrollability of the linearization.
