In this paper we described a menu-driven tool to construct multi-loop controllers that will then be automatically translated into real-time code. A standardized configuration is used for each controller and a Simulink model of the controller and display are automatically generated. It is envisaged that the display and command facilities will be on a separate machine from the real time control machine, so these are considered as a separate block.

The paper presents an approach how the important relationships between the actuator, process and design parameters furthermore robustness measures can be determined. In this decomposition method the optimal controldesign for two-degree of freedom time delay controlsystems is discussed. Using a proper CAD algorithm graphical relationships can be plotted and the ultimate robustness limit of any control can be explicitly calculated.

An extension of the variable parameterization method is presented. Conditions for switching generation and reduction are analysed. The previously used quasi-Newton algorithm is completed with the Newton method. The transversality conditions are modified The ideas are illustrated by a numerical example showing the performance of the algorithm also for singular cases. A comparison with direct and indirect collocation approaches is given.

We describe the model and controller reduction software recently developed for the control and systems library SLICOT. Based on the latest algorithmic developments, a powerful collection of Fortran 77 subroutines has been implemented to cover the relative error and frequency-weighted model reduction, as well as special controller reduction approaches. The new model and controller reduction routines are among the most powerful and numerically most reliable software tools available for model and controller reduction. To facilitate their usage in user friendly environments, easy-to-use and flexible interfaces have been developed to integrate them in MATLAB and Scilab.

A method of on-line constructing an optimal feedback control for linear and nonlinear systems is proposed. The idea of closed-loop solution is based on constructing a realization of optimal feedback in any concrete control process under unknown but bounded disturbances. The realization of the algorithm of closed-loop solution is oriented on fast corrections of optimal open-loop control subject to small variations of initial state. This is possible due to storage a small amount of additional information allowing to avoid the complete integration of primal or adjointsystem.

This paper describes an approach and implementation of a group of toolkits which are capable of converting and embedding a simulation model into an industrial target application. The method allows for Simulink discrete-time models to be automatically converted and executed in real-time as Supervisory control and Data Acquisition (SCADA) system modules or as subroutine blocks in the PLC leader diagram folder. This provides viability of the toolkits for rapid control prototyping for industrial applications. A number of examples illustrate the concept.

A computational optimization-based approach for designing fixed-order controllers is presented. The approach focuses classical pole placement design techniques for both certain and uncertain (interval) linear time-invariant plants within a goal programming framework. The design objective is the minimization of the overall deviation from the desired performance for the closed-loop system, as specified by a polytope of characteristic polynomials in the general case. Goal programming, a traditional technique in many different engineering design contexts, reveals to be an adequate basis for integrating a number of existing results in linear controller design by pole placement. Examples illustrate the main characteristics of the proposed approach.

The author presents a new approach within advanced graphics simulations for the problem of nano-assembly automation and its application for medicine. The problem under study concentrates its main focus on nanorobot autonomous control for molecular assembly manipulation and the use of evolutionary competitive agents as a suitable way to warranty the robustness of any proposed model. The presented paper summarizes distinct aspects of some techniques required to achieve a successful nano-planning systemdesign with a 3D visualisation in real time.

We propose a simple optimisation algorithm for designing fixed-structure controllers for highly-uncertain plants. The method can be used to automate the loop-shaping step of the QFT design procedure and guarantees robust stability and performance to the feedback loop for all parameters in the plant's uncertainty set. To avoid over-designing the system, the algorithm can be used to minimise either the asymptotic gain or the cross-over frequency of the open-loop system. Some preliminary results of this work have appeared in [9].
