    Globally stable control of linear systems with input saturation subject to L2 disturbances is analysed. The well known results on disturbance-free systems are that nonlinear controls can ensure global stability, while linear time-invariant controls can only achieve semiglobal stabilisation. A linear control with a tuning parameter is proposed to achieve global stability of the systems e... View full abstract»

    The error behaviour of the extended Kalman filter is analysed. It is proved that the estimation error remains bounded if the system satisfies a detectability condition and both the initial estimation error and the disturbing noise terms are small enough. Moreover, some selected cases with both bounded and unbounded estimation error are demonstrated by numerical simulations View full abstract»

    The CAN (controller area network) is a serial communication protocol for distributed real-time control and automation systems. Data generated from field devices in manufacturing automation and process control systems are classified into three categories: real-time event data, real-time control data and non-real-time data. These data share a common CAN medium. Unless the traffic of the CAN protocol... View full abstract»

    Cited by:  Papers (15)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (396 KB)

    An optimal control method is presented. The proposed controller is designed via combining classical state feedback control and variable structure control (VSC). This method fully matches the merits of the easy design of the linear quadratic (LQ) method and the strong robustness of the VSC. The presented optimal control method is demonstrated on a synchronous reluctance motor (SynRM). It is proved ... View full abstract»

  • Root distribution of delta-operator formulated polynomials

    Publication Year: 2000, Page(s):1 - 12
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (428 KB)

    Owing to its superior performance in high-speed signal processing/control, work on delta-operator based discrete time system implementations have attracted considerable attention. Stability and performance of such a system is closely related to the root distribution of its characteristic equation with respect to a certain `shifted' circle in the complex plane; the underlying sampling time determin...

    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (300 KB)

    The presented technique addresses the problem of maintaining the powerful design simplicity and visibility of eigenstructure assignment, while reducing closed-loop eigenstructure sensitivity to dominant parameter variations. The method results from consideration of the allowable eigenvector subspace as a complete description of the eigenstructure assignment problem. Variations in open-loop system ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (480 KB)

    The symmetric acausal/causal dichotomy for the linearised stable internal dynamics of a class of flexible manipulators is studied. Computational issues, including the convergence of the iterative computation scheme and the symmetry computation of the desired internal dynamic trajectory, are addressed and the implication of the noncausal invertibility on tip trajectory planning is investigated.

    Cited by:  Papers (14)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (260 KB)

    A predictive controller for constrained linear time-varying systems with polytopic uncertainty is presented. The algorithm minimises an upper bound on the predicted quadratic cost function with respect to the first few future control moves and a feedback gain that completes the description of the predicted input trajectory. The optimisation problem is shown to be a convex problem which can be form... View full abstract»

    Simple design methods are proposed for attaching compensators to improve the robustness of previously designed control systems in use. Robust model matching (RMM) is a practical approach to designing robust compensators. First, RMM is generalised and its standard design procedure is presented. Then, by considering the configuration of RMM, design methods for attachable robust compensators are sugg... View full abstract»

  • Parameter identification of continuous systems with multiple-input time delays via modulating functions

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (244 KB)

    The identification of continuous systems with multiple-input delays is discussed. A batch algorithm for parametric identification of both multiple time delays and unknown parameters is proposed using the modulating function approach. If the unknown delay is expressed as a linear combination of a bank of known delays, it is proven that the distribution of the identified coefficients is a sampling c... View full abstract»

    A new gain fusion algorithm is proposed for application to decentralised sensor systems. The proposed algorithm gives computer-efficient suboptimal estimation results, such that it reconstructs the global estimate and covariance from local Kalman filter gains and estimates without significant loss of accuracy. Compared to the conventional algorithm, the smaller communication requirement and the re... View full abstract»
