This paper considers the boundary control of a star-shaped open-channel network modeled by the Saint-Venant equations. We present the boundary feedback stabilization of the Saint-Venant equations by means of a Riemann invariants method. The estimation of the parameters satisfying the stability condition is deduced. The boundary feedback control is developed to guarantee that the solution of the controlsystem decays exponentially, only by taking the water levels at the gate boundaries as the feedback.

In this paper, a two-degree-of-freedom (TDOF) controller design method for multi-inputs multi-outputs (MIMO) system with multiple time delays based on inversing decoupling is proposed. Firstly, an inversing decoupling method based on the factorization of the plant is developed. Secondly, the H 2 optimal controller design method is applied to the decoupled single-input/single-output (SISO) system after the system has been decoupled. Finally, a TDOF controller is designed for the decoupled closed-loop system. Compared with other developed methods, the proposed design method has two main advantages. One is that the design procedure is simple and the obtained controllers are given in analytical form. The other is that better performance can be achieved since the TDOF control structure can isolate the disturbance from the reference. Simulations are provided to illustrate the effectiveness of the proposed design approach.

A computer vision based method was proposed to detect and track pedestrians. It worked on TLD (tracking-learning-detection) framework which was a target detection and tracking algorithm that runs the detection and tracking simultaneously and then integrated the results to update the detection and tracking modules. HOG (histograms of oriented gradients) operator and an incremental classifier based on NCC (normalized cross correlation) matching were proposed to improve the detector for the reason that TLD was prone to an error or failure when it was applied to track a pedestrian. Firstly HOG descriptor was calculated to match with the templates stored in classifier based on NCC, then the results were integrated with tracking module, and final results will be used to update the detecting module. According to the experimental results, this method has good robustness and efficiency.

In a phage λ genetic switch model, bistable dynamical behavior can be destroyed due to the bifurcation caused by inappropriately chosen model parameters. Since the values of many parameters with biological
significance often cannot be accurately acquired, it is thus of fundamental importance to analyze how and to
which extent the system dynamics is influenced by model parameters, especially those parameters pertaining
to binding energies. In this paper, we apply a Jacobian method to investigate the relation between bifurcation
and parameter uncertainties on a phage λ OR model. By introducing bistable range as a measure of system robustness, we find that RNA polymerase binding energies have the minimum bistable ranges among all the
binding energies, which implies that the uncertainties on these parameters tend to demolish the bistability
more easily. Moreover, parameters describing mutual prohibition between proteins Cro and CI have finite
bistable ranges, whereas those describing self-prohibition have infinity bistable ranges. Hence, the former are
more sensitive to parameter uncertainties than the latter. These results help to understand the influence of
parameter uncertainties on the bifurcation and thus bistability.

Along-Track Interferometric Synthetic Aperture Radar (ATISAR) has the potential of measuring the radial velocity of the slowly moving target. The accuracy of the radial velocity is mainly determined by the accuracy of the interferometric parameters. Sensitivity equations are good ways of analysing the impacts of system parameters for interferometric SAR. Former sensitivity analysis for ATI-SAR has been mainly focused on the case of no squint angle. In this paper, we explain the necessity of analysing the sensitivity equations in the presence of squint angle. Then the expression of the radial velocity in the presence of squint is derived and the sensitivity equations are obtained. Finally, the sensitivity of some interferometric parameters and the impact of squint angles are analysed and simulated for a particular accuracy requirement.

A stabilized Distributed MPC for large scale system is proposed and its designation is given in this paper for improving the global performance of closed-loop system. To make the performance of closed-loop system more close to that using centralized MPC, each subsystem-based MPC added the cost of the entire system into its optimization cost function. In addition, a consistency constraint and dual mode strategy are designed and adopted. Provided an initially feasible solution can be found, subsequent feasibility of the algorithm is guaranteed at every update, and the asymptotic stabilization is established.
