Various types and techniques of on-line approximation have been used in feedback control of uncertain nonlinear systems. In many practical applications, saturation of the control input influences significantly the performance of adaptive and learning control systems. This article addresses the issue of control input saturation in on-line approximation based control of nonlinear systems. A modif...

Input saturation is inevitable in many engineering systems. In this note, the focus is to design the proper iterative learning control algorithms when the desired trajectory cannot be realized within the saturation bound. Two new algorithms are proposed. First algorithm introduces a kind of “reference governor” which reduces the amplitude of the desired trajectory systematically such that the m...

Displacement of oil and water in porous media of reservoir rocks is described by relative                      permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...

This paper deals with the solution bounds for time-delay systems via delay-dependent Lyapunov– Krasovskiimethods. Solution bounds arewidely used for systemswith input saturation caused by actuator saturation or by the quantizers with saturation.We show that an additional bound for solutions is needed for the first time-interval, where t < τ(t), both in the continuous and in the discrete time. T...
