Diagonal Dominance Design of Mu&variable Feedback Control Systems using the Stability-equation Method
نویسنده
چکیده
A systematic procedure is proposed for the design of multivariable feedback control systems. For an N x N multivariable control system, the desirable overall compensator is decomposed into N cascaded sub-compensators to be determined in each step. The stabilityequation method is used to find the desirable sub-compensators. After step N, the overall closed-loop system can be designed diagonal dominant and have a desirable performance closely related to the characteristic roots of each subsystem. A 4 x 4 boiler furnace system is chosen as an example, and comparisons are made with methods in the current literature.

A Sequential Design Method for Multivariable Feedback Control Systems
In this paper, a sequential design method is proposed for analyses and designs of multivariable feedback control systems. The overall compensator is implemented systematiccally with a cascaded layer-wrapped structure and diagonal compensators. The method can take into consideration of stability, integrity, diagonal dominance and performance in a sequential manner. Roots of stability-equations a...
متن کاملQFT Control of a Two-Link Rigid-Flexible Manipulator
This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...

متن کاملMarkovian Delay Prediction-Based Control of Networked Systems
A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...
متن کاملDesign of decentralized PI control systems based on Nyquist stability analysis
This paper presents a simple, but effective, design method for decentralized PI control systems with guaranteed closed-loop stability. Nyquist stability conditions are used to derive the stability region for each PI controller in terms of the controller parameters. A detuning factor for each loop is specified based on a diagonal dominance index. Then appropriate controller settings are determin...
