This paper presents the current work on the development of a tool for remote control of mobile robots. The tool consists of a local controller on the robot side and a user interface for simulation and remote control that connects with the robot through the network. The user interface is implemented as an HTML page with a Java applet for remote control and communication and a virtual environment written in VRML for visualization. This way users have the ability to connect to a dedicated WWW server and download the user interface. This paper describes the concept of the tool design and the developed user interface. © 2003, Institute of electrical and Electronics Engineers Inc. All rights reserved.

The paper deals with the description of block-oriented nonlinear dynamic systems having multisegment piecewise-linear nonlinearities and with their identification using the Wiener model. A new form of multisegment nonlinearity representation and multiple application of a decomposition technique provides a special form of Wiener model with the minimum number of parameters. The model is linear in all the parameters to be estimated and is used in the proposed identification method. An illustrative example is included. © 2003 IFAC.

作者： Halas, Miroslav Huba, Mikulas Zakova, Katarina Department of Automation and Control Faculty of Electrical Engineering and Information Technology Slovak University of Technology Ilkovicova 3 Bratislava81219 Slovakia

The aim of this paper is to present a new method for the nonlinear controller design. The underlying theory evolves from the introduced transfer function of nonlinear systems, that can be used in similar way as transfer functions of classical linear systems. The presented algebra of transfer functions is the same as the linear one. Therefore, the controller design can follow the linear system synthesis. The paper shows, how to design a nonlinear PID controller using the direct method synthesis and also shows that the nonlinear state controller following the pole-placement method is equivalent to the exact linearization method. Since the presented method leads to results identical with the exact linearization method, it has been denoted as the exact velocity linearization method. © 2003 IFAC.

The high practical significance of the I1Td-plant approximations has been shown by the perhaps most frequently used method for controller tuning by (Ziegler and Nichols, 1942), modified later for sampled data systems by (Takahashi et al., 1971) and by many other authors. This paper extends previous works by developing plant approximations based on the single and double integrator models with dead time. These approximations are then used for tuning of the minimum time pole assignment P-(PD-) controllers designed for single (double) integrator with constrained input. © 2003 IFAC.

Reconfigurable control for ship steering

This paper is concerned with the application of a heuristic approach in the design of a fault-tolerant control system for ship steering. It proposes an advanced reconfigurable control system (RCS) for ship course changing/keeping and track keeping, robust to faults in actuator, gyrocompass and global positioning system (GPS) in the presence of disturbances (waves and currents). The proposed control scheme uses a reference model for compensation of signals from fault sensors and a compensator for reducing the loss of the control performance produced by a fault in the steering machine. In the case of the occurrence of the fault in one or more components, this control system minimizes loss in the control performance and gives enough time for operators to take appropriate action in order to reduce the risk of safety hazards and avoid severe consequences of the fault. The unavoidable penalty of degradation in control performance was found to be acceptable. © 2003 Institution of Mechanical Engineers.

The paper discusses possible ways how to incorporate an existing controller into the predictive control framework. This idea is used in anti-windup framework, where the performance can degrade in some cases. The basic requirements are to meet the performance of the nominal controller in the unconstrained case and to guarantee stability in the constrained case. © 2003 IFAC.

Long-range optimal prediction algorithms use the predicted output for several steps ahead. The prediction based on traditionally estimated model parameters does not result in an optimal prediction if the measurements are noisy or/and model structure differs from real process structure. In this paper two different identification schemes are presented and compared: long-range predictive single-model identification and simultaneous multi-step-ahead prediction identification. It is shown that the first method is easier to realize but the second one leads to more accurate results. Both methods are derived for a first-order model in details. Simulation runs and a level control example illustrate the algorithms presented. © 2003 International Federation of Automatic control.

/spl Lscr//sub /spl infin//-multipliers for robust performance analysis

引用

IEEE Transactions on Automatic control 2003年第6期48卷 1016-1018页

作者： M. Tanimou A. Linnemann Department of Electrical Engineering Control and Automation University of Kassel Kassel Germany

Linear systems subject to nonlinear time-varying sector-bounded uncertainties are considered. Robust performance is measured in terms of the worst-case ratio between the /spl Lscr//sub /spl infin//-norms of the output and input signals. A new class of multipliers is introduced and characterized. The characterization can be used to compute an upper bound for robust performance, which tightens the bound obtained by the scaled small gain theorem. While the standard Popov multipliers and their extensions have been developed within the /spl Lscr//sub 2/ framework, our multipliers are adapted to /spl Lscr//sub /spl infin//.

In this paper, a direct learning control method for a class of switched systems is proposed. The objective of direct learning is to generate the desired control profile for a newly switched system without any feedback, even if the system may have uncertainties. This is achieved by exploring the inherent relationship between any two systems before and after a switch. The new method is applicable to a class of linear time varying, uncertain and switched systems, when the trajectory tracking control problem is concerned. A numerical simulation demonstrates the effectiveness of the proposed method. © 2003 IEEE.
