  • Feedback linearisation of nonminimum singular systems

    Publication Year: 2001, Page(s):213 - 216

    Presents a solution for feedback linearisation of a class of nonlinear systems which have singularity and nonminimum phase. Traditionally, these two problems have been mentioned as shortcomings of standard feedback linearisation. In the proposed scheme, purposely introduced uncertainty under the matching condition yields stabilisable linear systems with vanishing perturbed terms. With additional L... View full abstract»

  • LMI approach to delay-dependent robust stability for uncertain time-delay systems

    Stability criteria are provided for a class of uncertain linear time-delay systems with time-varying delays. Based on Lyapunov-Krasovskii functionals combined with LMI techniques, simple and improved delay-dependent robust stability criteria given in terms of quadratic forms of state and LMI are derived. Examples show the performance of the application of the results presented View full abstract»

  • Adaptive stabilisation of extended nonlinear output feedback systems

    Publication Year: 2001, Page(s):268 - 272

    The paper deals with the adaptive stabilisation for a class of uncertain nonlinear systems whose nonlinear terms are functions of two state variables. The uncertainty is parametrised by an unknown constant parameter vector affined to smooth nonlinear functions. The model format considered in the paper can be viewed as an extension to the standard output feedback systems with nonlinear terms of the... View full abstract»

  • Global output regulation with minimum information of uncertain nonlinear systems subject to exogenous signals

    Publication Year: 2001, Page(s):203 - 208
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (492 KB)

    Deals with global output regulation of uncertain nonlinear systems affected by disturbances which are generated from a known exosystem. The information needed for the control design is that the uncertain system satisfies the geometric conditions for the output feedback form with stable zero dynamics and the parameterisation is linear for unknown constant parameters and the unmeasurable disturbance...

  • Time-domain based design and analysis of new PID tuning rules

    Publication Year: 2001, Page(s):251 - 261
    Cited by:  Papers (14)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1064 KB)

    The time domain PID analysis includes three types of first-order plus time delay (FOPTD) models: (a) zero or negligible time delay (b) low to medium long time delay and (c) very long time delay. The first part of the analysis proves that the optimum PID controller for plants having negligible time delay is a PI controller, and the corresponding PI terms based on the actuator's capacity and set-poi...

  • Inverse control of systems with hysteresis and creep

    Publication Year: 2001, Page(s):185 - 192

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (536 KB)

    Since the beginning of the 1990s, hysteresis operators have been employed on a larger scale for the linearisation of hysteretic transducers. One reason for this is the increasing number of mechatronic applications that use solid-state actuators based on magnetostrictive or piezo-electric material or shape memory alloys. All of these actuator types show strong hysteretic effects. In addition to hys... View full abstract»

  • Control of free length when coiling a helical spring

    Publication Year: 2001, Page(s):239 - 244
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (476 KB)

    The problem of controlling the free-length of a helical spring while it is being manufactured on an automatic coiling machine is examined. This is a disturbance rejection problem, and the feedback system is designed to reject disturbances caused by variation of the wire properties and disturbances generated by the coiler. Fixed, self-tuning and fuzzy self-tuning control are used to reduce the vari... View full abstract»

  • Nonlinear decoupled control for linear induction motor servo-drive using the sliding-mode technique

    Publication Year: 2001, Page(s):217 - 231
    Cited by:  Papers (14)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (976 KB)

    Presents a design for nonlinear decoupled control of a linear induction motor (LIM) servo-drive. An ideal feedback linearisation control (IFLC) system is first adopted in order to decouple the thrust force and the flux amplitude of the LIM. However, the control performance of the LIM is influenced seriously by the uncertainties of the plant, such as electrical and mechanical parameter variation, e... View full abstract»

  • Eigenstructure assignment design for proportional-integral observers: continuous-time case

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (400 KB)

    A complete parametric eigenstructure assignment design approach for proportional integral observers of multivariable linear systems is proposed. Based on a complete general parametric solution to the generalised Sylvester matrix equation, complete parameterisations for all the observer gains as well as the left eigenvectors of the observer system matrix are established in terms of three sets of de...

  • Intelligent backstepping control for linear induction motor drive

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (840 KB)

    The design and properties of an intelligent backstepping control system for a linear induction motor (LIM) drive to track periodic reference trajectories are studied. First, the dynamic model of a field-oriented control LIM drive is derived. Then a feedback linearisation controller is designed in the sense of the backstepping control technique. To relax the requirement for the bound of lumped unce... View full abstract»

    Following developments in the modelling and control of the output probability density function of dynamic stochastic systems, an approach for the controller design is presented using square root approximation, where a set of B-spline functions are used to approximate the square root of the measured output probability density function to guarantee its positiveness. A performance function is defined... View full abstract»

    Describes the development and practical application of a neurofuzzy controller that learns online to follow a time-varying set-point. It is shown that, during training, the control action is similar to that of a proportional plus integral plus derivative controller. A method for selecting the parameters of the learning scheme is proposed that does not require precise information about the open-loo... View full abstract»
