An adaptive fuzzy design for fault-tolerant control of MIMO nonlinear uncertain systemsJournal of Control Theory and Applications - Tập 9 - Trang 244-250 - 2011
Ping Li, Guanghong Yang
This paper presents a novel control method for accommodating actuator faults in a class of multiple-input multiple-output (MIMO) nonlinear uncertain systems. The designed control scheme can tolerate both the time-varying lock-in-place and loss of effectiveness actuator faults. In each subsystem of the considered MIMO system, the controller is obtained from a backstepping procedure; an adaptive fuz...... hiện toàn bộ
Optimal source rate control for adapting VBR video over CBR channelsJournal of Control Theory and Applications - Tập 4 - Trang 111-113 - 2006
Chunwen Li, Peng Zhu
In this paper we discuss the source rate control problem of adapting variable bit-rate (VBR) compressed video over constant bit-rate (CBR) channels. Firstly we formulate it as an optimal control problem of a discrete linear system with state and control constraints. Then we apply the discrete maximum principle to get the optimal solution. Experimental results are given in the end. Compared with tr...... hiện toàn bộ
Adaptive coordinated control of engine speed and battery charging voltageJournal of Control Theory and Applications - Tập 6 - Trang 69-73 - 2008
Jiangyan Zhang, Xiaohong Jiao
In this paper, the control problem of auxiliary power unit (APU) for hybrid electric vehicles is investigated. An adaptive controller is provided to achieve the coordinated control between the engine speed and the battery charging voltage. The proposed adaptive coordinated control laws for the throttle angle of the engine and the voltage of the power-converter can guarantee not only the asymptotic...... hiện toàn bộ
Identification of Hammerstein systems with asymmetric dead-zone nonlinearities using canonical parameterized modelJournal of Control Theory and Applications - Tập 10 - Trang 511-516 - 2012
Xiaohua Lü, Xuemei Ren
A non-iterative identification method with parameterization of the unknown dead-zone is proposed for Hammerstein systems in presence of asymmetric dead-zone nonlinearities. The canonical parameterized model which is a single expression without segmentation is utilized to describe the dead-zone, based on which a universal-type parametric model can be established to approximate the entire system.

Adaptive sampling immune algorithm solving joint chance-constrained programmingJournal of Control Theory and Applications - Tập 11 - Trang 237-246 - 2013
Zhuhong Zhang, Lei Wang, Min Liao
This work investigates one immune optimization algorithm in uncertain environments, solving linear or nonlinear joint chance-constrained programming with a general distribution of the random vector. In this algorithm, an a priori lower bound estimate is developed to deal with one joint chance constraint, while the scheme of adaptive sampling is designed to make empirically better antibodies in the...... hiện toàn bộ
Cooperative learning with joint state value approximation for multi-agent systemsJournal of Control Theory and Applications - Tập 11 - Trang 149-155 - 2013
Xin Chen, Gang Chen, Weihua Cao, Min Wu
This paper relieves the ‘curse of dimensionality’ problem, which becomes intractable when scaling reinforcement learning to multi-agent systems. This problem is aggravated exponentially as the number of agents increases, resulting in large memory requirement and slowness in learning speed. For cooperative systems which widely exist in multi-agent systems, this paper proposes a new multi-agent Q-le...... hiện toàn bộ

Decentralized adaptive synchronization of an uncertain complex delayed dynamical networkJournal of Control Theory and Applications - Tập 7 - Trang 225-230 - 2009
Weisong Zhong, Jun Zhao, Georgi M. Dimirovski
In this paper, we investigate the locally and globally adaptive synchronization problem for an uncertain complex dynamical network with time-varying coupling delays based on the decentralized control. The coupling terms here are bounded by high-order polynomials with known gains that are ubiquitous in a large class of complex dynamical networks. We generalize the usual technology of searching for ...... hiện toàn bộ
