Quantitative Non-diagonal Regulator Design for Uncertain Multivariable System with Hard Time-domain Constraints
author
Abstract:
In this paper a non-diagonal regulator, based on the QFT method, is synthesized for an uncertain MIMO plant whose output and control signals are subjected to hard time-domain constraints. This procedure includes the design of a non-diagonal pre-controller based on a new simple approach, followed by the sequential design of a diagonal QFT controller. We present a new formulation for the latter stage, which shows the role of off-diagonal elements in the design procedure. A numerical example is given to illustrate the effectiveness of the proposed method .

Robust Controller Design with Hard Input Constraints. Time Domain Approach
A novel approach to robust controller design with hard input constraints is presented. The proposed robust controller design procedure is based on the robust stability condition developed using Affine or Parameter-Dependent Quadratic Stability approach. The obtained feasible design procedures are in the form of BMI or LMI. The obtained design results and their properties are illustrated in simu...

This paper presents a robust controller design methodology for a class of linear uncertain multivariable systems with hard time-domain constraints on their outputs and control signals in response to step disturbance inputs. In this approach, the m×m MIMO system is replaced by m2 SISO systems and then, using the QFT technique, desirable controllers are synthesized. The final controller will be d...

full textControl of Multivariable Systems with Hard Constraints, Report No. 2348
A general framework for the design of multivariable control systems subject to hard constraints on each control channel is developed. The design procedure is an extension of the wellknown H∞ Loop Shaping Design Procedure and is based on the calculation of the maximum possible control amplitude for a certain class of reference signals. Special attention is given to the adaption of the design wei...
full textAchieving diagonal interactor matrix for multivariable linear systems with uncertain parameters
Akarae t -The notion of interactor matrix or equivalently the Hermite normal form, is a generalization of relative degree to multivariable systems, and is crucial in problems such as decoupling, inverse dynamics, and adaptive control. In order for a system to be input-output decoupled using static state feedback, the existence of a diagonal interactor matrix must first be established. For a mul...
