In this paper, a new data-driven ILC method is proposed for I/O constrained nonlinear systems. An iterative dynamic linearization is introduced for the controlled nonlinear systems. All of the constraints on the system inputs and outputs are reformulated with a linear matrix inequality. The learning control law is then developed by minimizing a predesigned cost function subjected to the linear matrix...
The purpose of this work is to attain a unified design framework of PID-like ILC with pure feedback structure for a class of nonlinear repetitive NARMA systems. To serving the controller design and analysis, the nonlinear NARMA system is transferred into a linear data model. Then, we suppose that there exists a desired nonlinear controller such that the system output tracks the desired output exactly...
The package-on-package (PoP) stacking assembly is a member of the SiP family. It is constructed by individual fabricated and tested packages from the same or different supplier provided in a stacked structure through solder joints. It can reduce the placement and routing areas on board and also allow one defective component to be replaced which is opposite to case of stacked Chip Scale Package (CSP)...
Executing task in the complex environment, the traditional RRT algorithm is easy to make the tree fall into local minimum area which resulted in poor efficiency. In order to solve the problem, this paper proposes an adaptive RRT algorithm based on dynamic step for path planning and uses the cubic polynomial BSpline curve fitting to smooth the plannned path. The simulation results show that the number...
The magnetic microscopy was successfully applied to localize the failure site of the failed SDP memory sample before the decapsulation of the failed sample. The magnetic microscopy pointed the specific (X, Y, Z) coordinate of the failure site and the failure site was confirmed by optical microscopy and SEM analysis. The failure analysis case demonstrated in this article showed the effectiveness of...
In order to improve the traffic guidance efficiency and the transportation quality of the road network, a traffic guidance model called Stackelberg-Logit Game Model is presented. It is a Stackelberg Game Model between traffic manager and travelers which combined two traffic assignment principles, the User Equilibrium and the System Optimum. Meanwhile, the Improved Logit Model is employed to calculate...
Most drivers often make route choices according to their preferences in our real life, and they have different requirements for different path attributes. In this paper, the problem for optimal path selection with driver's preference is studied and path selection algorithm based on Grey Incidence Decision is put forward. Firstly, a path selection index system was constructed in order to reflect the...
System in Package (SiP) technology is rapidly evolved from specialty technology used in a narrow set of applications to a high volume technology with wide ranging impact on electronics markets. Numerous concepts for three dimensional (3D) SiP packaging are now emerging driven largely by the demands of portable consumer products. Conventional failure analysis techniques face a great challenge for SiP...
System in Package (SiP) has become a popular technology along with the tendency of functionality and portability for electronic devices. Due to the complex design, dimension, and materials in SiP system, some of traditional failure analysis methods are not applicable any more, or have to be improved to meet the specific requirements of SiP structures. In this paper, some advanced techniques for failure...

Unlike traditional routing schemes that route all traffic along a single path, multipath routing strategies split the traffic among several paths in order to ease congestion. It has been widely recognized that multipath routing can be fundamentally more efficient than the traditional approach of routing along single paths. aiming at the increasing network traffic and the deficity that the former Ant...

The simulation results indicate that the algorithm has high convergence speed and reliability, and can meets the demand of QoS multicast in NGN well.
MPLS networks use label technique for data transmission, so the way of fault detection and restoration in MPLS networks are different from the way in traditional IP networks. An existing scheme called Haskin scheme applies a mechanism to send data reversely, which brings in heavy delay and makes packets out of order; The FRR scheme is implemented with RSVP TE protocol, it has ability to detect and...

The main objective of TPMA is to build a QoS...
In the MPLS-based mobile IPv6 network, when mobile node performs handover, it needs to rebuild label switching path, which impacts the handover delay and causes packets loss. Reused parts of the path overcome the above reasons, which propose a cross-router (CR) algorithm. It modifies the label information base (LIB), that is, increases two fields: the mobile node address and the time counter. When...
