Robust Controller Design and PID Tuning for Multivariable Processes
In this paper, a robust controller design method is first formulated to deal with both performance and robust stability specifications for multivariable processes. The optimum problem is then dealt with using a loop-shaping H∞ approach, which gives a sub-optimal solution. Then a PID approximation method is proposed to reduce a high-order controller. The whole procedure involves selecting severa...
متن کاملRobust Decentralized PID Controller Design
Robust stability of uncertain dynamic systems has major importance when real world system models are considered. A realistic approach has to consider uncertainties of various kinds in the system model. Uncertainties due to inherent modelling/identification inaccuracies in any physical plant model specify a certain uncertainty domain, e.g. as a set of linearized models obtained in different work...
متن کاملPID Controller Tuning for Stable and Unstable Processes Applying GA
During the last years the use of intelligent strategies for tuning Proportional-Integral-Derivative (PID) controllers has been growing. The evolutionary strategies have won an important place thanks to their flexibility. In this paper, the automatic tuning of systems with stable and unstable dynamics, through a genetic approach is presented. The advantages of the proposed approach ere highlight...
متن کامل"Controller Design with Real Parametric Uncertainty"
A number of techniques have been developed in recent years for the analysis and design of controllers which are robust with respect to structured complex uncertainty. In particular the complex p synthesis procedure has been successfully applied to a number of engineering problems. However the presence of real parametric uncertainty in the problem description substantially complicates matters, s...
متن کاملRobust Controller Design Techniques for Unstable Systems
The presented paper deals with simple and practical methods of discrete controller design using conventional approach based on robust stability analysis in frequency domain, and the new approach using the reflection vectors techniques. We assume that the control structure consists of feedforward and feedback part. Proposed algorithms were tested in illustrated examples for stable, unstable and ...
