This paper discusses the robustness and performance on H tree structure with canonical statistical timing model. We compare the deterministic skew and statistical skew to analyze the design health. With the sensitivity distribution available at the end of statistical timing, we make the robustness diagnostic to reveal key variation sources and optimization scheme. The skews under intra-chip variation...
IP Multimedia Subsystem (IMS) not only inherits the telecom advantages, but also brings several disadvantages, such as poor scalability, single point of failure, etc. Peer-to-Peer (P2P) network has the advantage of scalability and robustness, but there are some difficulties in the peer management and route optimization. By reusing the mechanism of signaling control and media negotiation in IMS, P2P...
Hypersonic vehicle is characterized by its high altitude, fast velocity, complex flight environment, big span of mach number, as well as its inability to foresee coming disturbance. Based on the needs to design large envelope flight controller, this paper employed LPV (Linear Parameter Varying) method to model the hypersonic vehicle, and utilized μ-synthesis to design gain scheduled robust controller...
This paper presents the robust ??2 and ???? step tracking control methods for networked control systems subject to random time delays modeled by Markov chains. To make full use of the delay information, the static output feedback controller to be designed is dependent on both sensor-to-controller and controller-to-actuator delays. Using the augmentation method, the resulting closed-loop system belongs...
A color image watermarking scheme based on support vector regression (SVR) is proposed in this work. Considering the characteristic of human visual system (HVS), the watermark information is embedded in the luminance channel of YCbCr color space. The luminance component of original color image is partitioned into contiguous blocks. Some blocks with small variance values are selected to train SVR to...
This paper discusses the problem of linear path following for an underactuated surface ship with rudder actuator dynamics under external disturbances. By employing T-S fuzzy system as approximator of those unknown nonlinearities, a robust adaptive fuzzy controller is proposed by fusion of ldquodynamic surface controlrdquo(DSC) approach with ldquominimum-learning-parametersrdquo(MLP) algorithm for...
The position of the engine throttle is driver's reflection to the vehicle power and the request of the vehicle speed. In the technical vehicle energy-saving automatic shifting gears control system, it is requested that the engine throttle position control system must have the precise position response, the higher speed of response, and the stronger stability and robust. The process of engine throttle...
