Optimal control of nonlinear systems: a predictive control approach [PDF]
, 2003 A new nonlinear predictive control law for a class of multivariable nonlinear systems is presented in this paper. It is shown that the closed-loop dynamics under this nonlinear predictive controller explicitly depend on design parameters (prediction time

Control theory for nonlinear fractional dispersive systems
, 2022 We consider a terminal control problem for processes governed by a nonlinear system of fractional ODEs. In order to show existence of the control, we first consider the linear counterpart of the system and reprove a number of classical theorems in the fractional setting (representation of the solution through the Gramian type matrix, Kalman's principle,

A new fault tolerant control scheme for non‐linear systems by T‐S fuzzy model approach
IET Control Theory & Applications, 2021 This paper is concerned with the problem of fault tolerant control for non‐linear systems with sensor faults based on the T‐S fuzzy model approach. First, a fault estimation (FE) observer with L∞ technique is designed to estimate the fault.
