On the nonlinear control of TCSC
Proceedings of the 35th Annual Hawaii International Conference on System Sciences, 2003The paper reviews modeling of thyristor-controlled series capacitors (TCSC) which are highly nonlinear systems with continuous and discontinuous states, and proposes three nonlinear controllers for it: (1) an approximate feedback linearization control (FLC); (2) a sliding surface-like design; (3) control in transformed coordinates.

Nonlinear control of helicopters
2001 European Control Conference (ECC), 2001This work focuses on the nonlinear control of helicopters. Our global interest is a general model (7-DOF) to be used on the autonomous forward-flight of helicopters. However, in this paper we present a reduced-order model (3-DOF) representing a scale model helicopter mounted on an experimental platform.

A mill is a mechanical device that grinds mined or processed material into small particles. The process is known to display significant deadtime, and, more notably, severe nonlinear behavior. Over the past 25 years attempts at continuous mill control have met varying degrees of failure, mainly due to model mismatch caused by changes in the mill process

Repetitive controllers are generally applied to reject periodic disturbances and to track periodic reference signals with a known period. Their design is based on the internal model principle, proposed by Francis and Wonham (1975). This paper describes a new finite-dimensional SISO repetitive controller for two different classes of nonlinear plants ...

This paper presents piecewise nonlinear control for piecewise Takagi-Sugeno fuzzy systems described by a local Takagi-Sugeno fuzzy model in each piecewise region. We provide a piecewise sector nonlinearity idea to construct a piecewise Takagi-Sugeno fuzzy model from given nonlinear dynamics.

Dynamics of Nonlinear Feedback Control
Neural Computation, 2007Feedback control in neural systems is ubiquitous. Here we study the mathematics of nonlinear feedback control. We compare models in which the input is multiplied by a dynamic gain (multiplicative control) with models in which the input is divided by a dynamic attenuation (divisive control). The gain signal (resp.

Set Computation for Nonlinear Control
Reliable Computing, 2004The paper discusses, for a nonlinear discrete-time system, the problem to determine a control sequence which has to satisfy given set-membership specifications for the state and output vectors, and which (sometimes) has to be robust under some type of perturbations.
