FTC Structures with Virtual Actuators and Dynamic Output Controllers

Tracking with Bounded Actuators: Scheduled Controllers

We extend a class of scheduled controllers, that were originally developed to address actuator saturation in the disturbance attenuation problem, to the problem of tracking of generally unknown signals. The main assumption is that some (possibly conservative) bounds be known for peak magnitude and rate of the tracking signal. Both state feedback for and static output feedback controllers are pr...

Control of Linear Systems Using Dynamic Output Controllers

The paper deals with the problem of control of continuous-time linear systems by the dynamic output controllers of order equal to the plant model order. The design procedure is based on a solution of the set of linear matrix inequalities and ensures the closed-loop stability using Lyapunov approach. Numerical examples are given to illustrate the design procedure and relevance of the methods as ...

Stabilization of Networked Control Systems via Dynamic Output-Feedback Controllers

This paper investigates the problem of stabilization of networked control systems via dynamic output-feedback controllers. The physical plant and the dynamic controller are in continuous time, and a communication channel exists between the output of the physical plant and the input of the dynamic controller. Three important communication features are considered: measurement quantization, signal...

Dynamic output feedback stabilization for systems with sector-bounded nonlinearities and saturating actuators

In the present work a systematic methodology for computing dynamic output stabilizing feedback control laws for nonlinear systems subject to saturating inputs is presented. In particular, the class of Lur’e type nonlinear systems is considered. Based on absolute stability tools and a modified sector condition to take into account input saturation effects, an LMI framework is proposed to design ...
