On the basis of the interaction law of IT resources and IT application capabilities, using collaborative theory point of view, IT resources and IT application capabilities coupling measure model is established, which involves the active function, coupling degree functions, coupled coordination function and IT resources and IT ability coupling evaluation index system. According to the model, combined...
This work investigates the consensus problem of a group of nonlinear agents over a fast-switching network. The communications between agents are bidirectional and time delay exists. The topology, which specifies the communications, is assumed to be switched within a finite set of topologies, reflecting a practical fast-varying network environment. Based on the Lyapunov functional stability theory...
This paper considers the problem of distributed node-to-node consensus for general linear multi-agent systems with switched pinning links. The control goal in the present work is to make each follower track the corresponding leader asymptotically under the condition that only a small fraction of followers can sense their corresponding leaders through some switched communication channels. By using...
In this paper, we deal with the stabilization problem for a class of switched nonlinear systems in lower triangular form subject to constraints on the state. To prevent state from transgressing the constraints, we employ the ideal p-times differentiable unbounded functions, which grow to infinity when their arguments approach domain boundaries. Based on the backstepping technique, we propose a constructive...
Due to nonlinear and strong coupling of coke ovens, a distributed reinforcement learning control algorithm based on a radial basis function (RBF) for gas collector pressure control was proposed, in which the discrete space was dealt with by RBF and the critic-actor method was used to update the parameters of search network and evaluation network of the controller. Moreover, the control strategies...
Hot strip rolling flatness and gauge complex system has the features of strong coupling, uncertainty and nonlinearity. To improve the control accuracy, a strip flatness and gauge decoupling control method is put forward based on QDRNN-PID. The simulation results compared to the traditional PID control show that the decoupling control strategy has better control effect, adaptive tracking ability and...
This paper focuses on the problem of cluster synchronization of a class of complex dynamical networks. Based on impulsive control theory and a comparison theorem, generic criteria for cluster synchronization are derived. It is shown that these criteria provide a novel and effective control approach to synchronize a general dynamical network to a cluster synchronization manifold by exposing the relationship...
The paper investigates the second-order leader-following consensus problem of nonlinear multi-agent systems via adaptive pinning control. Based on graph theory and the neighbor-based coupling rule, the adaptive pinning control strategy is proposed, the consensus condition is derived in terms of linear matrix inequalities. It is worth noting that this paper addresses that what kind of agents and how...
In order to deal with the inherent characteristics of an air-breathing hypersonic vehicle (AHV) including high nonlinearity, strong coupling, fast-time variability, under-actuation, parameter perturbations as well as uncertainties, the cascade decoupling technique based on the active disturbance rejection control (ADRC) is applied to design a tracking controller during cruise. The tracking strategy...
This paper studies the exponential input-to-state stability (e-ISS) for hybrid dynamical networks (HDNs) consisting of flow and jumping subsystems. Concepts of input-to-state exponent (IS-E) and event-ISS are proposed. By using the IS-E estimates of subsystems and the method of multiple Lyapunov functions and M-matrix theory, the e-ISS including event-e-ISS criteria are established for HDNs. The small-gain...
In this paper, aiming at solving the synchronous problem of multi-finger dexterous hand, we introduced the iterative learning control (ILC) algorithm into the control of the system's synchronous coupling error to ensure the synchronization between finger joints on the premise that the system have good performance. In addition, we introduce a Lyapunov-like composite energy function to analyse the stability...
For the nonlinear coupling control problem induced by the maneuver flying with high angle of attack of the hypersonic vehicle, the dynamic inversion is used to realize the decoupling of the attack angle and bank angle dynamics. For the model uncertainty, parameter perturbation and outer disturbance, the estimation and compensation of the disturbance moments is carried out by the extended state observer...
Currently, when tourists' demands of the standard massive tourism are transferring toward personal and systematic tendency, the original model of meeting demands by accommodation, travel, shopping, entertainment etc. is meeting with trouble. Tourism supply chain can assist tourism companies and partners in cooperating well. On the one hand, it integrates tourism factors and organizes tourism products...
Circulating fluidized bed boiler (CFBB) develops quickly for a large range of fuels, rapid adjustment to load instruction and low-emissions. But its combustion system is sophisticated with large time-delay and multi-input multi-output coupling together, which make it hard to control. Based on analyzing an existing 2×2 transfer function matrix of the main steam pressure and the bed temperature, a partial...
The yaw stabilization in distributed-motor drive electric vehicles is usually based on hierarchical control structure, namely an upper-level motion following controller and a lower-level control allocation scheme. The existing strongly coupling property of tire forces gives rise to extreme difficulty in solving the control allocation problem for its nonlinearities in the moment/effector relationships,...
To transform the Buck-Boost converter from the chaotic state to the periodic orbits, this paper proposes a chaotic control method by improving the correlation between the inductor current and the output voltage. By adjusting the coupling strength, this method can control the chaotic Buck-Boost converter to the period-2, period-4, period-8 orbits and the period-3, period-6, period-9 orbits, without...
The internal gas pressure of vacuum breaker (VCB) is a main influencing factor which effects on the VCB's electric properties. The decaying gas pressure in arc chamber will not only cause the supply voltage to be beyond the VCB's endurance, but also very difficult to cut off the fault current effectively. With the decline of the arc chamber's vacuum degree, because of the arc quenching performance...
