    A new approach to robust stabilisation of a class of sampled-data systems with nonlinear uncertainties is proposed. The case that the plant and the controller are connected via a network channel, which may be subjected to data packet dropout and communication delays is of particular interest. Such systems as continuous-time nonlinear systems with delayed input are modelled. Sufficient conditions o... View full abstract»

    Wing rock phenomena is a limit cycle roll oscillation experienced by aircraft with slender delta wings at a high angle of attack. A new reinforcement adaptive fuzzy control scheme is proposed for suppressing or tracking wing rock phenomena. A fuzzy logic system is used to approximate a unknown nonlinear dynamics in which a variable universe technique is applied to modify the premise parameters of ... View full abstract»

  • Eigenvalue assignment with optimal spectral conditioning by static output feedback

    Publication Year: 2005, Page(s):621 - 627
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (156 KB)

    This paper presents a method for the robust assignment of the eigenvalues of a linear system by static output feedback, based on the minimisation of the spectral condition number of the closed-loop dynamic matrix. The procedure relies on an assignment method recently proposed by the authors, that enables the explicit parameterisation of the set of the feedback gain matrices which assign the prescr...

  • Delay-dependent robust H controller design for uncertain descriptor systems with time-varying discrete and distributed delays

    Publication Year: 2005, Page(s):628 - 638
    Cited by:  Papers (8)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (206 KB)

    The design problem of a delay-dependent robust H∞ controller for uncertain descriptor systems with time-varying discrete and distributed delays is investigated. The designed controller can guarantee the closed-loop system is regular, impulse-free and exponentially stable with an H∞ norm bound constraint. The obtained criteria to derive an efficient robust H&i... View full abstract»

  • Successive-approximation approach of optimal control for bilinear discrete-time systems

    Publication Year: 2005, Page(s):639 - 644
    Cited by:  Papers (21)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (169 KB)

    A successive-approximation approach designing optimal controllers is developed for bilinear discrete-time systems with a quadratic performance index. By using the successive-approximation approach, the original optimal control problem is transformed into a sequence of nonhomogeneous linear two-point boundary-value problems. The optimal control law consists of an accurate linear term and a nonlinea... View full abstract»

  • Steering control of a hopping robot model during the flight phase

    Publication Year: 2005, Page(s):645 - 653
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (270 KB)

    Two different types of steering control strategies for a hopping robot model during the flight phase are presented. The first strategy presents a time-varying feedback law based on the model reference approach, where the trajectory of the extended system is chosen as the model reference trajectory. The controllers are designed in such a way that after each time period the trajectory of the hopping... View full abstract»

  • Low-hump sensitivity function design for dual-stage HDD systems with different microactuators

    Publication Year: 2005, Page(s):655 - 661
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (392 KB)

    The paper focusses on a control design that aims to achieve a low hump sensitivity function for dual stage servo systems in hard disk drives. Two microactuator models are studied, a MEMS (microelectromechanical system) actuator and a PZT (piezoelectric) actuator. A nearly flat sensitivity function is accomplished in the continuous-time domain for the dual-stage servo loop using the H∞ View full abstract»

  • H model reduction of linear systems with distributed delay

    Cited by:  Papers (8)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (306 KB)

    This paper is concerned with the problem of H∞ model reduction for linear distributed-delay systems. For a given stable system containing both discrete and distributed delays in the state, our attention is focused on the construction of reduced-order model of the same structure, which guarantees the corresponding error system to be asymptotical...

  • Computation of performance robustness bounds for control systems with parameter uncertainties: an LMI approach

    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (178 KB)

    The problem of computing an upper bound on the size of parameters to guarantee the β-boundedness of control systems with parametric uncertainties is focused. Based on an improved linear matrix inequality (LMI) representation of β-boundedness criteria for polytopic uncertain systems, this problem is transformed into a generalised eigenvalue problem, which can be easily tested with efficie...

  • Synchronised trajectory-tracking control of multiple 3-DOF experimental helicopters

    Publication Year: 2005, Page(s):683 - 692
    Cited by:  Papers (19)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1811 KB)

    A synchronised trajectory-tracking control strategy is proposed for multiple experimental three-degrees-of-freedom helicopters. The model-based controller includes a feedforward compensation term and a PD feedback control term. Asymptotic convergence is achieved for both trajectory tracking and motion synchronisation. A proposed generalised synchronisation error concept allows the design of differ... View full abstract»

  • H2 gain scheduled state feedback for LPV system with new LMI formulation

    Publication Year: 2005, Page(s):693 - 697
    Cited by:  Papers (26)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (133 KB)

    The H2 gain scheduled state feedback problem is considered by using the parameter-dependent Lyapunov function for linear parameter varying system, in which the dependent parameter is assumed to be measurable on-line in a polytope space. First, a new linear matrix inequality (LMI) representation provides a type of H2 cost computation for this system. With the introduction of the extra variable, thi... View full abstract»

  • Neural observer by coordinate transformation

    Publication Year: 2005, Page(s):698 - 706
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (246 KB)

    Nonlinear control affine systems with maximum relative degree and a class of nonlinear differential equations can be transformed into a state representation known as the normal form. Based on the normal form an observer is designed using neural networks as approximation of nonlinear terms in the normal form and the observer gain is determined with a previous result in a triangular form.

  • Delay-dependent stability criteria for uncertain neutral systems with multiple time-varying delays via LMI approach

    Publication Year: 2005, Page(s):707 - 714
    Cited by:  Papers (10)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (171 KB)

    The asymptotic stability conditions for a class of uncertain neutral system with multiple time-varying delays are considered. LMI-based delay-dependent criteria are proposed to guarantee the asymptotic stability of systems. Based on the results of this paper, the model transformation is not used in finding the delay-dependent results. Significant improvement for the delay-dependent results has bee...

  • Global positioning system receiver tracking-loop optimisation via an H approach

    Publication Year: 2005, Page(s):715 - 722
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (356 KB)

    The application of H∞ optimal control theory to global positioning system receiver tracking loops is investigated. The design of an H∞ controller for the receiver tracking-loop is presented. The H∞ controller is particularly attractive because it is a robust design in the sense that small disturbances lead to small tracking errors. Furthermore, it... View full abstract»
