Two-Stage Multivariable Antiwindup Design for Internal Model Control

Multivariable plants under input constraints such as actuator saturation are liable to performance deterioration due to problems of control windup and directional change in control action. In this paper, we propose a two-stage internal model control (IMC) antiwindup design which guarantees optimal closed loop performance both at transient and at steady state. The two-stage IMC is based on the s...

The Dynamical Analysis of a Delayed Prey-Predator Model with a Refuge-Stage Structure Prey Population

A mathematical model describing the dynamics  of a  delayed  stage structure prey - predator  system  with  prey  refuge  is  considered.  The  existence,  uniqueness  and bounded- ness  of  the  solution  are  discussed.    All  the  feasibl e  equilibrium  points  are determined.  The   stability  analysis  of  them  are  investigated.  By  employ ing  the time delay as the bifurcation parame...

Control of Time-delayed Lpv Systems Using Delayed Feedback

In this paper, the delayed (memory) feedback synthesis problem for linear parameter varying (LPV) systems with parameter-varying time delays is introduced and addressed. It is assumed that the state-space data and the timedelay depend continuously on the parameters which are measurable in real-time and vary in a compact set with bounded variation rates. Synthesis conditions for stabilization an...

Antiwindup-aware PI autotuning

This manuscript addresses the problem of “tuning the antiwindup mechanism” of PI(D) controllers, an issue seldom addressed in the literature but yielding improvement and reducing undesired large-transient behaviours if tackled correctly. A previously proposed framework is extended and related to both alternative antiwindup implementations and tuning methods, resulting in more methodological ins...
