The problem of non-fragile fault-tolerant guaranteed cost control is studied for a class of nonlinear networked control systems with time delays and packet dropouts. The system parameters are allowed to have time-varying uncertainties, and the actuator faults are assumed to occur in a random way. By utilizing Lyapunov stability theory and linear matrix inequality (LMI) methods, a sufficient condition...
By analyzing the relationship between the fore-scaling and post-scaling of the images' DC coefficients, this paper proposes a robust image watermarking arithmetic with scaling compatible in DCT domain. Hung together with the JPEG encoding course, this method embeds the watermark information into the DC coefficients after the discrete cosine transform and abstracts the corresponding information from...
A new method of Fuzzy PID-Iterative learning control of Electro-hydraulic servo system was proposed, which was formed by incorporating fuzzy control and iterative learning control with control law. The learning law parameters, which are previously determined in the conventional design method, are regulated adaptively by fuzzy ruler respectively. The control arithmetic is simple and easy to implement...
In this paper, we present a robust system to accurately detect and localize texts in natural scene images. For text detection, a region-based method utilizing multiple features and cascade AdaBoost classifier is adopted. For text localization, a window grouping method integrating text line competition analysis is used to generate text lines. Then within each text line, local binarization is used to...
Coupling multi-variable controller contains some problems of complex nonlinear control. Single neuron PID controller has a good capability of self-adapting, self-learning, nonlinear and robustness. This paper uses some single neuron PID controllers to design coupling multi-variable controller, accompanying a large amount of optimization problem of nonlinear multi-dimension complex function. To solve...
