This paper is concerned with the problem of robust decentralized output-feedback control for a class of continuous-time large-scale nonlinear systems. Each nonlinear subsystem, described by a Takagi–Sugeno model, involves in the interconnections and parametric uncertainties of the large-scale systems. The main focus of this paper is to design a robust decentralized static output-feedback (SOF) fuzzy...
The paper is concerned with the problem of robust filtering for a class of systems with state-dependent uncertainties and energy-bounded disturbance. The state-dependent uncertainties can more precisely describe many practical dynamic systems with parameters varying with system states, such as spring stiffness, nonlinear resistor and friction coefficient. A non-quadratic Lyapunov function is adopted,...
Advanced finite element dynamic substructuring tests using innovative signal-based control strategies are presented in this paper. Substructuring tests decompose an entire structural system into parts. Nonlinear and critical components are physically tested at full size, whilst the remainder is simulated numerically in real-time. The success of the tests depends on two major requirements: (1) a robust...
A color image oblivious watermarking scheme based on neural network and discrete wavelet transform (DWT) is proposed in this paper. Three identical watermarks and some different expanded bit streams are adaptively embedded into the low frequency sub-bands generated from three channels for a color image, respectively. Due to the adaptive learning capabilities of neural network, the expanded bit streams...
