The robust connective stabilization problem for a class of interconnected large scale systems with arbitrary expanding construction, in which the new subsystems with arbitrary dimension are added, is studied in this paper. This problem is how to design the local decentralized control law of the new arbitrary subsystem based on not changing the decentralized control laws of original construction, so that both the subsystem and the resultant expanded system are connective stable. In the past literature, the research results are only aimed at the subsystems with same dimension. Further, the expansion problem for the subsystem with different dimensions is solved in this paper. The dispose method about different dimensions is given. The sufficient condition of the robust connective stabilization for the expanding construction of the systems is obtained by taking Lyapunov theory and LMI approach. The design Method of the robust decentralized connective stabilization controller of the expanding construction is given. The control simulation results for a class of power system modol with expanding construction show the effectiveness of presented method.

This paper studied a new method of ROI extraction based on quaternion matrix. Firstly, the image is cut into sub-blocks, and the Candidate region is gained by image entropy. Then the greatest expression of sub-blocks is obtained by svd of quaternion matrixs, and the relationship between the image blocks is found according to the definition of quaternion inner product. At last, dimensionality reduction of incidence matrix is carried out with Isomap, and in this process the ROI is extracted. The results of experiments confirm the feasibility and efficiency of this method.

A standard perspective image can be represented with part center area of an omnidirectional image from Micusik [12], can we generalize a few camera calibration methods from the perspective image to the omnidirectional image using part information in the center area of the omnidirectional image? In this paper, a novel omnidirectional camera calibration based on the approximate factorization method from multiple images is presented. This method first performs the approximate projective factorization algorithm using part of image points, which are less distorted than other feature points, in the center area of the omnidirectional image. Then, assuming zero skew and the principal point at the center of omnidirectional image, the initial value of camera intrinsic parameters can be computed. Last, the distortion intrinsic parameters are refined on minimizing the objective function. We demonstrate this method in experiment with synthetic data and real fisheye images.

Parallel kinematic planer is a new type of PKM. For PKM, dynamic character analysis is important to the mechanism's control. The paper reviews the conceptions of the PKM's dynamic and its analyses method. The paper describes a kind of 4-dof parallel kinematic mechanism with D-H method. By utilizing Newton-Euler approach, the dynamic model of the mechanism is developed, and meanwhile the detailed calculation process is present too. Finally the paper simulates the dynamic model with the Matlab software. The simulation results indicate the mechanism's dynamic character and are same as actual process controlling.

In this paper, a necessary and sufficient condition for the controllability of multi-agent systems under the switched topology is proposed. The connection between consensus and controllability of multi-agent systems under both the fixed and switched topology is discussed. The results show that the multi-agent systems can reach to a consensus if the system is controllable. The simulations verify the results.

The space vector pulse width modulation (SVPWM) exhibits unique advantages when applied to Permanent Magnet Linear Synchronous Motor (PMLSM) control systems. In the paper, principle and algorithm of SVPWM and mathematical model of PMLSM are analyzed. Simulation model of Frequency Conversion Timing Control System is set up by MATLAB/SIMULINK for PMLSM based on SVPWM algorithm. This provided a good simulation platform to analyse the running characteristics of PMLSM. At the same time, we carried out the actual operation on the PMLSM based on SVPWM control strategy. The simulation results as well as experiment results show that the control system is accurate and practicable even though load disturbance and perturbation of parameters exist.

An improved fourth order nonlinear diffusion filtering method is presented. An edge-detection function is introduced and the new method can adjust the diffusion speed adaptively. Compared to some previous high order filtering, the proposed method can preserve edges while denoising. Experimental results demonstrate the performance of the new fourth order nonlinear diffusion method.

An novel object detection and segmentation algorithm is proposed based on contour information and inference. The scheme proceeds in mo stages, in the first stage, some prototypes are learned automatically from their 3D models and training images. Firstly, aiming to viewpoint invariance, a two-layer structural of multi-views is built, secondly, the corner-polygon (CP), which is combination of 3 features, is proposed for describing templates. In the second stage, the generated framework is used for detecting category-given object. A new Dynamic Bayesian network (DEN) model is built to infer detection probability, based on corresponding patch matching and inference computing, the candidate window s should be found out, then thin plate spline (TPS) technique is used to segment object from background. Experimental results demonstrate that our proposed approach is able to identify and accurately detect and segment the objects with better performance than the existing methods.

For a biologically inspired mechanical system consisting of multiple segments, its natural oscillation is defined as a periodic body movement pattern conforming to the dynamics inherent to the body-environment interaction, leading to an effective locomotion of the system. In the literature, a central pattern generator based controller has been designed to approximately achieve entrainment to a natural oscillation. This paper further refines the previous result by proposing a controller that achieves exact entrainment, as well as a rigorous stability analysis which leads to a complete solution to the problem of entrainment to natural oscillation.
