  • Local asymptotic convergence of a cycle-free persistent formation of double-integrators in three-dimensional space

    Publication Year: 2012, Page(s):692 - 696

    We present local asymptotic convergence analysis for a cycle-free persistent formation of double-integrator modeled agents moving in three-dimensional space. Due to the absence of an available common sense of orientation, the agents sense the relative-displacements of their neighbors only with respect to their own local reference frames whose orientations are not aligned, and control the norms of ...

    This paper presents several forms of performance measures for the evaluation of the obstacle detection using an overlapped ultrasonic sensor ring. Due to beam overlap, the detection zone of each ultrasonic sensor can be divided into three sub-zones, and also for a given obstacle distance, the uncertainty arc can be divided into three sub-arcs. First, considering obstacle detection range and effici... View full abstract»

    In this paper, a Fuel Cell (FC) Maximum Power Point Tracking (MPPT) with fuel flow optimization is developed. The aim of this study is to extract the maximum power from a FC at different fuel flow rates and to protect the FC from over-current and voltage collapses across terminals. The system is composed of a tracker with a buck converter able to change the impedance and therefore the FC power. In... View full abstract»

    This paper considers n-agent cyclic polygon formations of mobile autonomous agents in the plane. The aim of each agent is to maintain a desired distance from its neighbor. Since the formation graph is directed, only one agent is responsible for maintaining each distance. The control law for each agent is designed in distributive manner. Hence, it utilizes only local information. We use gradient-li... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (351 KB) | HTML iconHTML

    In this paper we introduce an online algorithm that uses integral reinforcement knowledge for learning the continuous-time Nash game (zero-sum and non-zero-sum) solution for nonlinear systems with infinite horizon costs and partial knowledge of the system dynamics. This algorithm is a data based approach to the solution of the coupled Hamilton-Jacobi equations and it does not require explicit know... View full abstract»

  • Adaptive reduced-order control of discrete repetitive processes with iteration-varying reference signals

    Publication Year: 2012, Page(s):1238 - 1243
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (624 KB) | HTML iconHTML

    Discrete repetitive processes (DRPs) operate iteratively on a fixed-length time window or trial, with the feature that the state and output on each trial are driven by the output of the previous trial. This class of systems includes the case of iterative learning control (ILC). Typical control algorithms in ILC and DRP produce N-th order closed-loop systems, where N is the trial length. Here we ma... View full abstract»

  • Optimal iterative learning control with uncertain reference points

    Publication Year: 2012, Page(s):1244 - 1248
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (109 KB) | HTML iconHTML

    In this paper, we present two iterative learning control (ILC) frameworks for multiple points tracking problems. First, we present an ILC scheme to produce output curves that pass close to the reference points without considering the reference trajectory. Here, the control signals are generated by solving an optimal ILC problem with respect to the points. Second, we propose an optimal ILC multiple... View full abstract»

    Fuzzy systems identification suffers from “rules explosion”, i.e., the number of fuzzy rules grows exponentially with the increase of the dimension of the input variable. In this paper, a dynamic algorithm is exploited to address T-S fuzzy systems identification on the basis of sparsity regularization. With a dynamic increase of fuzzy rules, this method automatically extracts fuzzy r... View full abstract»

    This paper presents the optimal design of an overlapped ultrasonic sensor ring for high performance obstacle detection, using a new composite design index. Due to the beam overlap among adjacent ultrasonic sensors, the obstacle detection zone of each ultrasonic sensor can be divided into three smaller sub-zones. To improve the performance in obstacle detection, the state of beam overlap of an over... View full abstract»

  • Robust fault isolation using dynamically extended observers

    Publication Year: 2012, Page(s):1201 - 1206
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (208 KB) | HTML iconHTML

    In this paper we propose a new method to design robust fault isolation observers (FIOs). The technique exploits the duality between non-interacting control and observer-based fault isolation and provides additional degrees of freedom by means of dynamically extended observers. A general procedure to design such observers is given. The additional design variables are then exploited to increase robu... View full abstract»

    This contribution deals with the design of fault isolation observers (FIOs). Their purpose is to detect and isolate faults acting on linear systems by means of only a single observer. While parameterizations for such observers have been proposed for statically isolable systems, we generalize the existing results to linear systems without the restriction of a non-singular fault detectability matrix...

    In decision making problems, experts need to assess a number of values in a side of reference domain higher than in the other one,that is, experts use unbalanced linguistic values to express their evaluation for problems. In this paper, we propose a new linguistic aggregation operator to deal with unbalanced linguistic values in group decision making. Based on 2-tuple representation model of lingu...

    Interconnected power grid becomes more complex and tends to be vulnerable to unwanted disturbances; thus, transient stability of the power system becomes an important research topic. In this paper, we propose a control law that not only enhances the transient stability but also makes the system to satisfy output synchronization. The key idea of this paper is that the power system can be realized a... View full abstract»

    Self-reconfigurable robots are versatile machines composed of many small, computationally independent modules. If a large number of modules is available, they can divide into multiple smaller robots instead of remaining as one large group. In such a case, they must decide based on their mission whether and when such a division is appropriate, and if so, how to divide the mission objectives amongst... View full abstract»
