41st IEEE Conference on Decision and control

作者： Zhu, Yucai Control Systems Section Faculty of Electrical Engineering P.O. Box 513 5600 MB Eindhoven Netherlands Tai-Ji Control Grensheuvel 10 5685 AG Best Netherlands

Estimation of some nonlinear ARX models is studied. First the model structures are discussed and their numerical tractability examined. Three NARX models are proposed. Parameter estimation is solved for the three models. A relaxation iteration scheme is proposed by using the model structures in which the error is bilinear-in-parameters. The convergence and consistency of the methods are established. Simulation study will be used to illustrate the method.

In this paper, we present a feedforward control system using adaptive PI strategy for a positioning mechanism with stand. Due to the rapid motion of a moving table, the vibration phenomena in a stand may be induced by the reaction force of a motion of a moving table. However in previous research, the dynamics of the stand does not consider. Besides, in such a system, rapid and accurate positioning of a moving table is required for the high productivity and quality. To cope with this problem, we present the dynamic model of the positioning mechanism with stand using linear slider, apply a feedforward control method with adaptive PI control strategy to the system and show the effectiveness of our method, compared to the conventional research.

This paper proposes the time space MUSIC technique using the chirp pulse signal of a tracking radar. Direction/time of arrival (D/TOA) estimation characteristics are evaluated for the simulated point sources, simulated extended air targets, and the actual extended air targets. It is shown that the proposed technique is enable to highly resolve and precisely estimate D/TOA of the actual targets covered by one radar beam width.

A laser induced breakdown spectroscopy (LIBS) technique has been applied to detect the unburned carbon in fly ash, and an automated LIBS unit has been developed and applied in a 1000MW pulverized coal fired power plant for real-time measurement of unburned carbon in fly ash. Good agreement was shown between measurement results from the LIBS method and those from the conventional method(JIS 8815), with a standard deviation of 0.27%. This result confirms that measured unburned carbon in fly ash using LIBS is accurate enough for the boiler control and boiler control in optimized way is possible using the value of unburned carbon content in fly ash. © 2002 OSA/LIBS.

Distributed control systems (DCSs) are shifting from conventional specialized models such as gas turbines, steam turbines, *** more flexible unified models. DCSs are expected to eventually be integrated with remote operation/monitoring and designwork. We have developed DIAsYS Netmation, a next-generation DCS that features high information orientation and *** will be used to monitor/diagnose plants using Internet as ped of after-sales service. We also have developed DIASYS-IDOL++, a design tool that totally integrates DCS from plant design to system engineering.

This paper presents an approach to fast object manipulation by dextrous re-grasping of multi-fingered hands. The approach is based on a real-time grasping force optimization (GFO) algorithm and a fingertip impedance control scheme. Both the controller and the GFO make use of 6D contact force sensor data at run-time. The latter keeps the contact forces as small as possible while considering friction limits at the contact points during (re)grasping. The impedance controller is used to impose the optimized contact forces onto the grasped object while simultaneously enabling active control of the fingertip positions. Experiments demonstrate the robustness of the approach and the increase in task speed during multi-fingered manipulation.

The paper presents the design of spatial control system of a large pressurized heavy water reactor (PHWR) with the constraint that the closed loop system be stable even if one output sensor has failed. Linear state models are obtained corresponding to the normal operating condition and different failure modes of the reactor. Each model is found to possess two time scale property. Application of a standard singular perturbation approach decouples the fast varying modes which are ignored to eliminate the stiffness. Thus a reduced model is obtained for each operating mode of the reactor. Convex programming is used to search for an output injection gain which stabilizes all reduced models simultaneously. This output injection gain is then realized simultaneously in all operating modes by a controller based on periodic output feedback.

We consider an adaptive PI controller for a positioning mechanism with stand. To control the position of a moving table with vibration suppression of the stand, derivation of the motion equation of the whole system and identification of the physical parameters are very important. However, in previous researches, conventional PI control methods have been applied to the positioning control and the design parameters depend heavily on the physical parameters of the controlled system. To cope with this problem, we apply the adaptive PI control strategy to that system and show the effectiveness of our method, compared to the conventional strategy.

The total supervisory control and data acquisition (SCADA) system has been developed for the Okutataragi Pumped Storage Power Station and its substation. The system applies an open distributed client-server computer architecture and the state-of-the-art man-machine devices, such as a large mimic displays and CRTs with mouse operation. It also includes the following operator support functions: a fault tree based operator guidance function, a bearing temperature prediction function, and a vibration monitoring function. The SCADA system has been put into commercial operation where its superior capabilities have allowed the entire power station and its substation to be run by only two operators.
