This paper aims to utilise a model of the surrounding field together with measured data therefrom to locate and orientate an observer. A single valued solution is developed to calculate the position of a vehicle in a continuous field environment described by a known polynomial, from a minimum number of equispaced field measurements taken at that location and known coefficients of the polynomial. Where insufficient measurements from a single scan of the field are available, a formula for utilising extra data from several scans has been produced. The robustness of these algorithm, when the observation process is corrupted by Gaussian white noise, is also addressed.< >

The paper considers the problem of stabilizing large scale dynamic systems (LSS) via decentralized controllers based on Variable Structure systems (VSS) and using the principle of dominant subsystems. The principle and applications for LSS are described and simulation test results on a two- machines power system with nonlinear model are presented.
The observed polarisation of the horizontal magnetic components of whistler mode signals received at Halley, Antarctica (L≈ 4.3), is in many cases that expected from a simple model of the transionospheric and sub-ion...

The authors present a practical solution to the problem of real-time robot control including the nonlinear dynamic model of the manipulator by employing a parallel processing approach. The parallelism inherent in the adaptive controllers is exploited to obtain an efficient implementation that reduces the overall computation time to within the limit acceptable for real-time control. The distributed algorithm is implemented on a network of transputers for the six-joint PUMA 560 arm.< >

This paper addresses the design of a selftuning controller for linear and non-linear dynamic systems. Modelling of nonlinear dynamic systems is realized using the expanded Voltera kernels by orthonormal Laguerre functions in a continuous and a discrete form. A predictive nonlinear control law is derived on the base of the Laguerre polynomials in a recursive form. The proposed control law has many benefits (simple use. easy handling of varying time delay and nonminimum phase behaviour, etc.). The method outlined in this paper presents new trends in design of control of nonlinear plants using selftuning DDC algorithms. The theoretical part of the paper presents several modifications of modelling and control algorithms design yielding new results with proof of convergency properties for Laguerre spectra estimation procedure. Practical problems solutions are involved.

The supervisory control problem in the discrete event dynamic systems (DEDS) is formulated using input-state-output system structure. A class of the Petri nets is defined enabling an effective and practically useful representation of the structural and dynamic properties of DEDS. A solution of the supervisory control using the Petri nets and the corresponding reachability graphs is presented and illustrated on an example.

Current computer aided control system design environments seldom support optimization methods for controller design in a truly interactive manner. A prototype tool, called PARSIM, supporting parallel processing, optimization and a graphical user interface is presented addressing many of the problems inherent in current approaches to multiobjective optimization based design methods. An XWindows interface is used to simplify problem formulation and control the optimization processes. Using a previously developed interface, the computational burden may be alleviated by parallel processing.< >

This paper introduces a framework of tools which allow the design of distributed, potentially fault-tolerant, real-time control software. This framework takes a system specified in the controlengineering domain and translates this application-oriented representation into a software engineering representation. From this new representation, automatic code generation tools have been developed to create a complete, executable control system implementation.< >
