Among the many techniques for designing linear multivariable analogue controllers, the two
most popular optimal ones are H2 and H-infinity optimization. The fact that most new …

Research in robust control theory has been one of the most active areas of mainstream
systems theory since the late 70s. This research activity has been at the confluence of …

Linear matrix inequalities (LMIs) have emerged recently as a useful tool for solving a
number of control problems. The basic idea of the LMI method in control is to interpret a …

Direct digital design of general multirate sampled-data systems is considered. To tackle
causality constraints, a new and natural framework is proposed using nest operators and …

This paper considers an H 2 optimal control problem for sampled-data systems. After
defining a new H 2 norm for sampled-data systems, we give a state space solution to the …

This paper considers a continuous-time linear system with finite jumps at discrete instants of
time. An iterative method to compute the L_2-induced norm of a linear system with jumps is …

This book gives an introduction to H-infinity and H2 control for linear time-varying systems.
Chapter 2 is concerned with continuous-time systems while Chapter 3 is devoted to discrete …

For active vibration control of powertrain oscillations, the purpose of this research is to
present a simple fuzzy-reasoning-based compensation strategy for a time-varying control …

Digital elements such as signal processors, microcontrollers or industrial PCs are widely
used for filtering and control of continuous-time processes or plants. Because of the serial …

Recently, a frequency-domain operator called frequency response (FR) operator was
defined and shown to represent the transfer characteristics of a stable sampled-data system …
