DESIGN OF NONLINEAR CONTROLLERS FOR NONLINEAR PLANTS

IFAC Proceedings Volumes, 1990
Abstract The paper describes three methods for designing nonlinear phase lead/lag controllers to be used in cascade with nonlinear plants to provide closed loop responses which are essentially amplitude independent. The approach requires amplitude dependent frequency response descriptions of the nonlinear plants, makes use of the describing function ...

On the nonlinear control of TCSC

Proceedings of the 35th Annual Hawaii International Conference on System Sciences, 2003
The 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), 2001
This 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.

Nonlinear mill control

ISA Transactions, 2001
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

Nonlinear repetitive control

IEEE Transactions on Automatic Control, 2000
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 ...
