In this paper, a kind of output feedback adaptive pinning controller is designed for the synchronization of state-coupling and output-coupling complex dynamical networks, where some states are immeasurable. The adaptive coefficients are related to the property of controlled nodes, different from the past researches in which they were simply set as constants. Based on Lyapunov stability theory, synchronization...
The combustion system is a large inertia, pure delay, nonlinear distributed parameter system. The control effect of PID regulator and dual cross limiting PID control in the combustion system is not satisfactory; the conflict of the overshoot and response time can not be resolved with relatively poor anti-interference ability of the system. In the control of the roaster, by adopting the method of combining...
Submerged arc furnace is a system with strong coupling, nonlinearity and time-variability. In this paper, a logistic-interpolation-based fuzzy controller for electrode regulation of submerged arc furnace is proposed. The proposed controller is based on fuzzy logic control strategy, and interpolation algorithm is employed to improve the control accuracy without raising complexity of the controller...
Flexibility, parameter uncertainty and joint friction restrict the control performance of flexible joint robots. In this paper, an adaptive backstepping method with friction compensation is presented for the control of flexible joint robots with parameter inaccuracies, in which the joint friction is described by LuGre model and compensated base on a friction observer, and the inaccuracies of robot...
Coverage and control problems of diffusion process using multiple mobile sensors and actuators have been considered in this paper. Algorithms for task allocation and obstacle avoidance have been considered for the mobile robots in this paper. The powerful tool of Centroidal Voronoi Tessellations (CVT) has been introduced in the partition of the workspace so that the robots can detect and detoxify...
In this paper, the design of delay-dependent H∞ controller for a class of singular Lurie systems with state-delay is studied. Delay-dependent sufficient condition is obtained in terms of matrix inequalities to ensure the resultant closed-loop system regularity, free of impulses, global uniform asymptotically stable and a prescribed H∞ performance. Furthermore, an LMI based state feedback H∞ control...
More and more intelligent buildings have been built in the world during last 10 years, but, according to application investigation in China, the intelligent level was not high and building control had not achieved the valued result, especially in intelligent control operation and energy saving for buildings, hi BAS (Building Automation System), there are many sub-systems integrated together with multiple...
This paper proposes a new approach to reduce the data transmitted in networked control systems (NCSs) via model reduction method. Based on the controllability and observability of the remote controlled plant, the “unimportant” information of system states vector is truncated by balanced truncation method (BTM) before sending to the controller via network. The exponential stability condition of the...
this paper is concerned with Hopf bifurcation behavior and bifurcation control of a new Lorenz-like system. Firstly, Hopf bifurcation type is studied based on the bifurcation stability norm, furthermore bifurcation period and characteristic exponent of system are given. Then the linear controller and the non-linear controller are applied to control the Hopf bifurcation of original system respectively...
Port competitiveness mainly depends on its profit. Port profit is affected by management measures. How to increase port competitiveness under the premise of the same port soft and hard environment is the main purpose for port managers. In order to meet the requirement, this paper takes three steps to build a benign competition relationship. Firstly, the indictors which influent the port profit are...

An image fusion method is presented to give a natural daytime color appearance fusion image in a simple way. Instead of using the traditional non-linear color transfer fusion method, the proposed method uses linear space and constant parameters to reduce the compute time and example images' influence on the fusion result. Through analyzed the impact of changes of the example images' means and variances...
Different attitude control systems for large-scale morphing flight were developed based on active disturbance rejection control. For the introduced longitudinal parameter-dependent flight dynamics, an attitude control system was developed with a novel control strategy, virtual morphing control surface, put forward. The un-modeled dynamics and aerodynamic error were observed and compensated as a generalized...
Data clustering is one of the most popular techniques in data mining. The attributes of the objects within the same cluster should be similar to each other, while the attributes of the objects within different clusters should be different. Most of classical clustering algorithms suffer from such disadvantages as local optima, initial centroid selection and the lack of a way to automatically determine...
To the problem that current real-time Ethernet POWERLINK cannot implement cross-communication, this paper proposes a scheme to implement cross-communication based on mastering the real-time Ethernet POWERLINK. The cross-communication between any two nodes in the network can be achieved by customizing the protocol stack of the real-time Ethernet POWERLINK and configuring the network parameters. Cross-communication...
With the diversification and personality of customer demand the modern chemical Polyester production has shifted to multi-product small batch production. The problem of the scheduling on multi-product small batch production is a new unresolved issue which is that people have been concerned about. This paper firstly analyzes the nature of the polyester engineering process and the optimal characteristics...
Currently, domestic dangerous chemicals are always stacked in the warehouse, there is no an effective method for monitoring the five distances in the storage that are subject to the safety standards—pile spacing, wall spacing, zenith distance, column spacing and lamp spacing. The research on timely monitoring and early alarming of dangerous chemicals stacking is necessary. In this paper, the indoor...
Burning Through Point (BTP) state is a very important parameter for sintering process. A lot of researches for the modeling of BTP have been made, but the precise model is not very easy to find, so the prediction based on modeling cannot be carried out effectively. This paper presents fuzzy neural network structure and multiple model algorithms which can process incomplete, ambiguous information and...

Technological innovation as the carrier, it analyzed knowledge innovation, talent development and the coupling evolution mechanism in the different stages of technology innovation. Using composite DEA method, it made a comparative evaluation about coupling evolutionary...
This paper concerns the robust reliable guaranteed-cost H∞ control problem for delta operator switched linear systems with actuator faults. The upper bound of the guaranteed-cost function is determined and the closed-loop system can be guaranteed some H∞ performance by using time and state switching control approaches. Finally, a simulation example is provided to illustrate the proposed methods.
