This paper suggests a method for designing PSS to damp multi-machine power system oscillations.  The method is based on robust control theory. First, the conventional method for designing robust controller in LMI framework is illustrated. Then, the suggested method is given, in which, a PID output feedback controller is tuned using the LMI approach. Mostly, the classical methods are used t...

This paper considers the design of robust, nite-horizon and innnite-horizon H 2 estima-tors based on multliplier theory (which is intimately related to the mixed structured singular value). Speciically, the Popov-Tsypkin multiplier is used to develop a novel upper bound on a nite-horizon, cost function for the assumed uncertainty set. The results are then applied to develop design equations for...

Abstract: This paper presents a new procedure for discrete-time robust structured control design. Parameter-dependent nonconvex conditions for stabilizable and induced L2-norm performance controllers are solved by an iterative linear matrix inequalities (LMI) optimization. A wide class of controller structures including decentralized of any order, fixed-order dynamic output feedback, static out...

This paper addresses the system identification problem, as well its application to robust fault detection, considering parametric uncertainty and using zonotopes. As a result, Zonotopic Recursive Least Squares (ZRLS) estimator is proposed compared with Setmembership (SM) approach when applied taking reference minimum detectable generated in worst-case. To illustrate effectiveness of parameter e...

A class of nonlinear models combining a pharmacokinetic compartmental model and a pharmacodynamic Emax model is introduced. The locally D-optimal (LD) design for a four-parameter composed model is found to be a saturated four-point uniform LD design with the two boundary points of the design space in the LD design support. For a five-parameter composed model, a sufficient condition for the LD d...

Robust design uses the parameter design approach of Genichi Taguchi to optimize designs of products and processes with the objective of building in insensitivity to noise. Noise is any kind of uncontrolled variation in the environment of operation of the product or process that could affect performance. If we recognize how variation in the environment (e.g., energy source, raw materials, heat a...
