This paper proposes a computational adaptive optimal output feedback control method for continuous-time linear systems. By periodic sampling, we use measurable input/output data to reconstruct the unmeasurable state, and then utilize adaptive dynamic programming (ADP) technique to iteratively solve the discrete-time algebraic Riccati equation. An exploration noise is introduced for online learning...
This paper is concerned with the design problem of robust fault-tolerant controller of linear uncertain satellite attitude control systems. The design method of output feedback robust fault-tolerant controller with failures of actuators and sensors is proposed to meet the given control performance by using LMI method. A numerical example of satellite attitude fault-tolerant control system is given...
For the anisotropic parabolic equations, we introduce a multilevel wavelet-like block incremental unknowns (WBIU) method and then, based on this new method, we construct a WBIU-type Crank-Nicholson scheme. The stability of this scheme is carefully studied. The numerical results show that the condition number of the coefficient matrix of the linear system correspond to this scheme is reduced efficiently...
