Prescribed-Time Tracking Control of MIMO Nonlinear Systems With Nonvanishing Uncertainties
IEEE Transactions on Automatic Control, 2023It is highly desirable yet challenging to achieve zero-error tracking within a given short time period for uncertain multi-input–multi-output (MIMO) nonlinear systems. Previous results are primarily state-regulation oriented and are valid only for single-

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

Robust nonlinear control of a variable-pitch quadrotor with the flip maneuver
Control Engineering Practice, 2019This paper presents robust nonlinear control of a variable-pitch quadrotor with the flip maneuver. Backstepping approach is chosen for nonlinear control design. A control allocation loop dynamically computes the blade pitch angle of each rotor.

In this note, we propose a novel adaptive fixed-time control scheme for output tracking problems of a class of multi-input multi-output (MIMO) nonlinear systems with asymmetric output constraint requirements, using a new universal barrier function. It is

DESIGN OF NONLINEAR CONTROLLERS FOR NONLINEAR PLANTS
IFAC Proceedings Volumes, 1990Abstract 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 ...

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.
