In this paper, we consider the robust sliding mode control problem for a class of systems with norm bounded parametric uncertainty and external disturbance. Based on Lyapunov stability theory and linear matrix inequality approach, the proposed control scheme can achieve both asymptotic stability and some robust performances, and the corresponding robust controller that assures the occurrence of sliding...
In this paper, we consider the fault estimation problem of non-uniformly sampled system with actuator faults and bounded disturbances. First, after being discretized at sampling instant, the non-uniformly sampled system is modelled as an equivalent polytopic system with norm bounded uncertainties. Then, a full-order discrete-time observer that has the same structure of a Kalman filter is constructed...
Recently, a new robust adaptive beamforming (RAB) technique was proposed to remove the signal of interest (SOI) component from the sample covariance matrix based on interference-plus-noise covariance matrix reconstruction, which utilizes the Capon spectrum estimator integrated over a region separated from the direction of the SOI. However, the extreme condition of the reconstruction-based technique,...
The accuracy of control allocation algorithms relies on control effectiveness matrix. To address this issue, this paper focuses on the robustness of control allocation. Several existing robust control allocation algorithms are analyzed at first. Then performance evaluation criteria for robust control allocation, which are designed for flight control, are proposed based on performance requirements...
