  • Optimal control of a ballast-stabilized floating wind turbine

    Offshore wind energy capitalizes on the higher and less turbulent wind speeds at sea. The use of floating structures for deeper waters is being explored. The control objective is a tradeoff between power capture and fatigue, especially that produced by the oscillations caused by the reduced structural stiffness of a floating installation in combination with a coupling between the fore-aft motion o...

  • Numerical simulation of continuous-time stochastic dynamical systems with noisy measurements and their discrete-time equivalents

    Computer-aided control system design software packages offer several numerical methods to simulate continuous-time (CT) deterministic dynamical systems. However, simulating stochastic dynamical systems (SDSs) has not received as much attention. This paper presents a self-contained treatment of how to simulate linear time-invariant CT SDSs with noisy measurements. The system model considered is qui... View full abstract»

    This paper addresses the problem of bond graph methodology as a graphical approach for modeling wind turbine systems. In this case, we consider the modeling of a wind turbine system with individual pitch control scheme and the interaction with tower motions. Two different bond graph models are presented, one complex and one simplified. Furthermore, the purpose of this paper is not to validate a sp... View full abstract»

  • A performance-oriented, non-iterative, local design method for mismatch-based anti-windup compensators

    Publication Year: 2011, Page(s):1056 - 1061
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (288 KB) | HTML iconHTML

    This paper proposes a local and - in contrast to existing synthesis approaches - non-iterative and performance-oriented design method for linear, full-order, mismatch-based anti-windup compensators which is applicable to control systems with unstable plants. Non-iterative means that the anti-windup compensator is found by solving a convex optimization problem. Hence, initial guesses or trial-and-e... View full abstract»

  • Maximally reduced observers for linear time varying DAEs

    The problem of observer design for descriptor systems, or systems of differential algebraic equations (DAEs) as they are also known, has been studied in the linear time invariant case. However, those studies do not readily extend to general linear time varying descriptor systems. Recently there have been new theoretical results and algorithms for computing completions of DAEs. In this paper we exa... View full abstract»

  • A new condition and equivalence results for robust stability analysis of rationally time-varying uncertain linear systems

    Uncertain systems is a fundamental area of automatic control. This paper addresses robust stability of uncertain linear systems with rational dependence on unknown time-varying parameters constrained in a polytope. For this problem, a new sufficient condition based on the search for a common homogeneous polynomial Lyapunov function is proposed through a particular representation of parameter-depen...

  • Online identification of switched linear output error models

    In this paper, we describe a modified recursive least squares (RLS) algorithm for the online identification of switched linear systems (SLSs). For this problem, a real time mode detection (MD) method is usually employed to detect the running mode for each output data and this part is very important for the estimation results. In fact, it is rather difficult to design a perfect MD method that can i... View full abstract»

    This paper addresses robust consensus problems among multiple agents with uncertain parameters constrained in a given set. Specifically, the network coefficients are supposed polynomial functions of an uncertain vector constrained in a set described by polynomial inequalities. First, the paper provides a necessary and sufficient condition for robust first-order consensus based on the eigenvalues o... View full abstract»

  • Dynamic resource allocation in urban settings: A “smart parking” approach

    Publication Year: 2011, Page(s):1 - 6
    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (308 KB) | HTML iconHTML

    We propose a “smart parking” system for an urban environment based on a dynamic resource allocation approach. The system assigns and reserves an optimal resource (parking space) for a user (driver) based on the user's objective function that combines proximity to destination with parking cost, while also ensuring that the overall parking capacity is efficiently utilized. Our approach... View full abstract»

  • Robustness preserving antiwindup: Examples and counterexamples

    An anti-windup scheme is said to be robustness preserving if it inherits the robustness properties of the corresponding unsaturated loop. It has recently been shown in the literature that anti-windup based on internal model control preserves robustness against additive uncertainty. In this paper we illustrate examples where other anti-windup schemes are also robustness preserving. We also demonstr... View full abstract»

    We consider the problem of approximating discrete-time plants with finite-valued sensors and actuators by deterministic finite memory systems for the purpose of certified-by-design controller synthesis. We propose a control-oriented notion of input/output approximation for these systems, building on ideas from classical robust control theory, and we explain the relevance of the proposed notion of ...

  • LFT-free μ-analysis of LTI/LPTV systems

    Publication Year: 2011, Page(s):638 - 643
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (679 KB) | HTML iconHTML

    μ-analysis has for many years been the de facto standard robustness analysis tool in a wide variety of control applications. To use μ-analysis, the uncertain system must be cast in the form of a linear fractional transformation (LFT). Once it is appropriately transformed, a variety of algorithms are available to calculate the upper and the lower bounds on μ. Several difficulti... View full abstract»

    We summarize some recent results on the dynamic stability of wholesale electricity markets. We discuss how to construct control-theoretic market analysis frameworks using concepts of market efficiency, Lyapunov stability, and predictive control. Such frameworks can be used to design, analyze, and monitor the stability and robustness properties of different market designs. In particular, we discuss... View full abstract»
