Investigates robustness of linear periodically time varying (LPTV) control of discrete linear time invariant (LTI) plants subject to LTI unstructured perturbations. The note first derives a necessary and sufficient condition for robust stability of an LPTV system subject to LTI perturbations, which is less conservative than the well known small gain condition. It then presents a quantitative analysis on the robustness of LPTV control under LTI unstructured perturbations in comparison with that…

Discrete-Time Noncausal Linear Periodically Time-Varying Scaling for Robustness Analysis and Controller Synthesis
Since modeling of real plants inevitably gives rise to modeling errors regarded as uncertainties, considering robustness for the uncertainties is important in actual control problems. For tackling
Robust Performance Controller Synthesis Based on Discrete‐Time Noncausal Linear Periodically Time‐Varying Scaling
This paper is concerned with the technique called discrete-time noncausal linear periodically time-varying (LPTV) scaling for robust stability analysis and synthesis. It is defined through the
Robust Observer-Based Output Feedback Control of a Nonlinear Time-Varying System
A class of time-varying systems can be quadratically stabilized with satisfactory performance by a modified time-invariant-based observer by derived from the minimi‐ zation of the cost of error dynamics with modified least-squares algorithms.

This chapter is to describe the numerical simulation and computer modeling work in aortic arch aneurysm, one of the most complex flow situations found in the cardiovascular system.


On the robust stability of linear time-invariant plants with unstructured uncertainty
We consider general families of linear time-invariant plants described by a nominal plant model with unstructured uncertainty. We show, under a rather weak assumption, that when a family of systems
Nonlinear time-varying controllers for robust stabilization
In this paper we consider the problem of robust stabilizallon for a certain class of plants with unstructured, infinite-dimensional uncertainty. We demonstrate that for the problem of robustly
Analysis of H2 and H∞ performance of discrete periodically time-varying controllers
Analysis of the H 2 and H ∞ performance of discrete linear periodically time-varying controllers for control of linear time-invariant plants shows that the multiple transfer channels of the system time-Varying dynamics amplify the overall system gain.
Robust control of linear time-invariant plants using periodic compensation
This paper considers the use and design of linear periodic time-varying controllers for the feedback control of linear time-invariant discrete-time plants. We will show that for a large class of
Robust stabilization of sampled-data systems to structured LTI perturbations
Sampled-data systems with stable, structured, LTI (linear time-invariant) perturbations in the half-plane algebra applied to the continuous-time plant are considered and the small gain theorem can be an extremely conservative robustness test in this sampled-data context.
Analysis of time-varying control strategies for optimal disturbance rejection and robustness
Analysis of linear time-invariant systems that are controlled by time-varying controllers is given. The problems of disturbance rejection and robustness are formulated and analyzed using functional

This paper considers the control of a linear time-invariant plant by a digital controller composed of a sampler. a periodic discrete-time component, and a zero-order hold. The stability of such a
Periodic Control of Linear Time-invariant Systems - A Critical Point of View
Abstract The use of periodic control in various forms has a long history in the control literature. It has been argued that a periodic feedback gain or controller when applied to an LTI system can
Time-varying versus time-invariant compensation for rejection of persistent bounded disturbances and robust stabilization
It is shown that time-varying compensation does not improve the optimal rejection of persistent bounded disturbances. This result is obtained by exploiting a key observation that any time-varying
Periodic discrete-time systems: stability analysis and robust control using zero placement
A simple method (based on Floquet theory) for obtaining the characteristic equation (and hence stability) of periodic discrete-time systems is presented. Using this method it is shown that 2-periodic
