In recent years, more and more technical systems dispose of some form of intelligence which allows to control and diagnose the processes and states in such systems. One important prerequisite for both control and diagnosis is monitoring, i.e. a systematic observation, surveillance or recording of entities of a technical product or its surroundings by any technical means. Current investigations were able to clarify that the design of a technical system can ease the control and diagnosis of this system. The same is true for monitoring;this fact will be demonstrated in this paper on the example of a research vehicle which is intended to foster the development of mapping systems and algorithms. In a sense, the main objective of this vehicle is also a kind of monitoring. Due to its unique design, this vehicle is able to navigate on all kind of terrains. It is equipped with several forms of sensors, which are consciously mounted at certain positions on the vehicle in order to allow a detailed detection of the surroundings. The investigation, how design can ease monitoring, was supported by a well-known model of product concretization and concrete insights could be found on all levels. © 2019 Design Society.

Many behavioural (Arkin, 1998) and deliberative (Russell and Norvig, 1995) robot control methods have been developed. Besides investigating task execution by a single robot multi-agent systems are being developed. Unfortunately only some of those control methods have a formal description. To aggravate the situation, those control methods that have formal specifications use different formal means of description. This paper presents an outline of a unified formal description of systems composed of many embodied agents using behavioural or deliberative control methods. Such a description is needed to specify in an implementation independent way the functionality of programming frameworks (Markiewicz and Lucena, 2001). Transition function based approach to the formal description of the above mentioned systems has been assumed to facilitate the future implementation of thus specified programming frameworks. The presented description is a generalization of the formal description used for the specification of MRR0C++ (Zieliñski, 1999;Zieliñski, 2001).

1999 European control Conference, ECC 1999

An algorithm for steady-state optimising control of technological processes within a multilayer control structure is considered in the paper, applicable to the situation when only an approximate and rather rough steady-state process model is available and disturbance estimates are uncertain. It is known that in such cases a single process model optimisation can lead only to very suboptimal results. The algorithm performs iterative set-point optimisation (improvement) using the model and process measurement information to cope with the uncertainty. It belongs to the ISOPE class (Integrated System Optimisation and Parameter Estimation). Further, a case with active constraints on process outputs vital for economical efficiency is considered, with an additional dedicated feedback correction controller used to keep the constraints satisfied. A two-phase dual-type ISOPE algorithm derived for the considered control structure is presented in the paper. It removes the major drawback of the available dual algorithm - inefficiency of the initial phase. Simulation results on a case study example of distillation columns in series are presented, for both new and previous algorithms. © 1999 EUCA.

2009 10th European control Conference, ECC 2009

The paper discusses an approach to configure a sensor network in a spatial domain that will be used to identify unknown parameters of a distributed system. Particularly, given a finite number of possible sites at which sensors may reside, we select gauged sites so as to maximize a criterion based on the Fisher information matrix associated with the estimated parameters. The technique is based on a relaxation of the original discrete optimization problem and amounts to operating on the density of sensors in lieu of individual sensor positions. Then, through an adaptation of some pairwise communication algorithms a numerical scheme is developed, which distributes the computational burden between the network nodes. As a result, a simple exchange algorithm is outlined to select the gauged sites in a decentralized fashion. The approach is verified on a numerical example involving sensor selection for a two-dimensional convective diffusion process. © 2009 EUCA.

computationally efficient nonlinear predictive control based on RBF neural multi-models

Lecture Notes in Computer Science

作者： Lawryńczuk, Maciej Institute of Control and Computation Engineering Warsaw University of Technology ul. Nowowiejska 15/19 00-665 Warsaw Poland

ISBN: (纸本)3642049206

This paper is concerned with RBF neural multi-models and a computationally efficient nonlinear Model Predictive control (MPC) algorithm based on such models. The multi-model has an ability to calculate predictions over the whole prediction horizon without using previous predictions. Unlike the classical Nonlinear Auto Regressive with eXternal input (NARX) model, themulti-model is not used recursively inMPC, the prediction error is not propagated. The presented MPC algorithm needs solving on-line only a quadratic programming problem but in practice it gives closed-loop control performance similar to that obtained in nonlinear MPC, which hinges on on-line non-convex optimisation. © Springer-Verlag 2009.

This work is concerned with tuning a nonlinear Model Predictive control (MPC) algorithm. Typically, the weighting coefficients associated with the predicted control errors are constant for the consecutive sampling instants over the prediction horizon. This work discusses a tuning procedure whose objective is to find a set of coefficients which scale the influence of the consecutive predicted control errors. The coefficients are determined using an original simulation-based method. In order to demonstrate effectiveness of the method, an MPC algorithm for vehicle obstacle avoidance is developed. It is shown that the discussed tuning methods makes it possible to obtain much better control quality in comparison with the classical approach. © 2020, Springer Nature Switzerland AG.
