In actual systems, actuator saturation is a common phenomenon, which often severely restricts system dynamic performance and gives rise to instability. In order to reduce the effects of saturation, this paper presents an adaptive control method based on multilayer neural networks (MNNs) for a class of uncertain nonlinear systems with Brunovsky canonical form and input saturation. This controller is...
This paper considers linear time invariant discrete-time tracking control systems with actuator saturation, and proposes a design procedure of discrete-time nonlinear dynamic controllers satisfying a regional integral quadratic performance. Our approach is based on the generalized sector approach and the linear matrix inequality technique. This paper clarifies that the design problem of the compensators...
This paper presents a wavelet based adaptive observer based control strategy for a class of uncertain multiple input multiple output (MIMO) delayed nonlinear systems subjected to actuator saturation. The time delay observer presented in this paper is the extension of observer design for SISO systems. The proposed wavelet adaptive observer performs the task of identification of unknown system dynamics...
This paper investigates the design problem of robust fault-tolerant control (FTC) by using online control re-allocation for a class of uncertain systems and its application to flight tracking control. The design procedure consists of two parts: robust fault-tolerant baseline controller design, and realization of a control re-allocation scheme. The baseline controller is obtained by an iterative LMI...
