  • Singular-value-decomposition approach to multivariable generalised predictive control

    A change of basis, from the standard set to the set of eigenvectors, provides the means for the decomposition of a multivariable problem into a set of scalar problems. This idea was deployed in an earlier paper to embed scalar generalised predictive control into the multivariable framework. Eigen-decompositions, however, can be sensitive to perturbations and cannot be applied to nonsquare matrices... View full abstract»

  • Hybrid adaptive control for tracking of rigid-link flexible-joint robots

    Publication Year: 1993, Page(s):155 - 159

    A hybrid adaptive tracking controller for rigid-link flexible-joint (RLFJ) robot manipulators is designed. The controller is hybrid in the sense that an adaptive indirect controller is used to compensate for parametric uncertainties in the rigid-link equation whereas an adaptive robust controller corrects for the dynamics and parametric uncertainty associated with the actuators. That is, in spite ... View full abstract»

  • Recursive technique for computation of Gramians

    Publication Year: 1993, Page(s):160 - 166

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (426 KB)

    A simple recursive method for the computation of Gramians for stable linear continuous systems is proposed. The method is based on an extension of Astrom-Jury-Agniel algorithm. The algorithms for the computation of controllability, observability, and cross Gramians for both SISO and MIMO systems are presented. The proposed method is illustrated by numerical examples and is also compared with the L... View full abstract»

  • Robust low-order control design of a generic flexible test structure

    Publication Year: 1993, Page(s):167 - 175
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (644 KB)

    The design of robust low-order controllers based on a high-order model of a generic flexible space test structure with collocated sensors/actuators is considered. A new synthesis technique which combines the projective and the positive-real control concepts is developed and used for control design. The proposed method alleviates the known difficulty of the projective approach where the residual (n... View full abstract»

  • Using self-organising feature maps for the control of artificial organisms

    Publication Year: 1993, Page(s):176 - 180

    Variations on the standard Kohonen feature map can enable an ordering of the map state space by using only a limited subset of the complete input vector. Also it is possible to employ merely a local adaptation procedure to order the map, rather than having to rely on global variables and objectives. Such variations have been included as part of a hybrid learning system (HLS) which has arisen out o... View full abstract»

  • LQG predictive optimal controller for continuous-time systems

    Publication Year: 1993, Page(s):181 - 190
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (735 KB)

    The LQG optimal continuous-time control philosophy is extended so that use may be made of future setpoint or reference signal information. The tracking error is defined in terms of an ideal response model so that a model following capability may also be introduced. A dual criterion cost function is employed that enables the feedback and reference input controllers to be designed independently. The... View full abstract»

  • Adaptive compliant control for an inspection robot system

    Publication Year: 1993, Page(s):191 - 197
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (555 KB)

    A robotic sub-sea inspection system is described. Emphasis is placed on how to use self-tuning adaptive control strategies to control the robot compliant motion. Experiments on a PUMA robotic manipulator have shown that adaptive control can greatly improve contact quality and provide much better tracking ability in an unknown environment. Also adaptive controllers can make the approach time shorte... View full abstract»

  • Application of polynomial array method to discrete-time system stability

    The method of polynomial arrays may be effectively utilised in determining stability of polynomials containing literal coefficients. In the paper, the application of the polynomial array method to discrete-time systems is further investigated. Using tabular forms by Bistritz (1984) and by Premaratne and Jury (1993), both shift-operator and delta-operator formulated discrete-time systems are addres... View full abstract»

    Illustrates the use of parallel processing to simulate dynamical systems described by a complex high-dimensional set of ordinary differential equations. A substantial paradigm problem is drawn from the nuclear industry to illustrate the use of an integrated parallel processing methodology. This includes heuristic rules for algorithm and architecture selection, a classification for decomposition te... View full abstract»

  • Automatic tuning of optimum PID controllers

    The paper first briefly reviews the analytical procedures for obtaining optimum PID controller settings for minimisation of time weighted integral performance criteria. The approach is then used to obtain formulae for setting the controller parameters for a first-order plus dead time plant model which is a common approximation used in the process industries. These results are further extended to o... View full abstract»
