The proposed method is based on the application of the well-known least mean squares (LMS) methods to their filtered linear regression models. As a result, its implementation requires neither the information of acceleration nor high-pass filtering of velocity, in contrast with the direct application of the LMS methods to on-line identification of single-DOF motion control systems. Most importantly, we show that the existence of steady-state oscillation can assure the persistent excitation (PE) property for parameter convergence. As a matter of fact, in practical applications, the existence of steady-state oscillation can be easily guaranteed by periodic excitation. The generality and practical use of the proposed method are demonstrated through some simulation results.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

Using an example of battery charging wind turbine system, we develop its model. In this model, we introduce damping as a component of the restraining moment. This is a novel concept that is not used in the current wind turbine designs. To investigate the merit of this concept, we perform a simulation study using the RPM-Sim simulator. The study shows that such damping improves the response but we should consider a trade-off between maximizing the wind power capture and minimizing the fatigue damage effects that result from the bang-bang operation. Then, we study the battery charging system with the peak power tracker (PPT). Finally, we present a simulation study of two utility-connected wind turbine systems with furling. We considered the operation of the system without and with the PPT. In the first case study, we use the gain of a DC/DC converter to implement the peak power tracking. In the second case study, we eliminate the DC/DC converter.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

In this paper analyze the effect of the parasitic elements of the output filter capacitor, to the output voltage and the load current slew rate of the switching power supply at the fast load transient. We found that the under-shoot of the output voltage in the sudden load change is not varied with the types of output filter capacitor (not depends of ESR, ESL and C). The output voltage drop in recovery is varied remarkably with the ESR of the capacitor and the load current slew rate is greatly varied with the ESL of the capacitor. The comparing three kinds of output filter capacitors; electrolytic, OS-CON and LILC (low-impedance line component), it realized that newly developed LILC significantly improved the transient response of voltage regulator module. The LILC is a newly developed capacitive component with very low impedance even at high frequencies. Simulation and experimental results are presented to verify the analysis.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

In this paper it will be shown that in three phase electrical systems the instantaneous power waveform presents symmetries if 1/6, 1/3, 1/2 or 1 cycle of the power system fundamental frequency, depending on the system being balanced or not, and having or not even harmonics (interharmonics and subharmonics are not considered in this analysis).

However, as quick flexible manipulators are essential to achieve this performance leading to a minor production time and small energy consumption, more resourceful control algorithms must be implemented, which can cope with important parameters variations, such as inertia. On the other side, even if predictive control has proved to be an efficient control strategy in industry, the maintenance of a high level of performances may be impossible to reach with a fixed predictive controller in case of important parameters variations. A solution is then to develop an adaptive version of the predictive controller for systems with parametric disturbances. This paper presents a direct version of adaptive generalized predictive control. The algorithm is rewritten in an original form minimizing a performance index, using a least-squares type strategy for the controller parameters on line identification and including a conditional updating test in the adaptation loop. An application of this structure to a robotic joint is finally developed, and a comparison between fixed predictive control and adaptive predictive control strategies stresses the advantages of adaptation in case of important inertia variations.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

The new exponential model depends upon two parameters, which can be basically determined by means of two strategies. In both cases, the user has a very simple, accurate and fast numerical simulation model, mainly free of convergence errors. The paper shows how to estimate both parameters in order to build both strategies in the Pspice 9.1 student version. A comparison between the two approaches is then made, using two different lamp powers, revealing very similar results regarding the voltage and current amplitudes as well as the waveform shapes.

Transport network means that the network applications are linked independently of the physical network technologies. The multihoming, multistream and chunk capabilities, present in the SCTP can be used for the guarantee of the aspects of temporal and spatial consistence, and redundancy. The SCTP protocol introduces a new network layer able to handle multimedia applications. The monitoring of many activities in the industry nowadays is provided by graphical simulation of the process. The SCTP can provide access to the process real time image by the use of cameras, which can send the image stream through the network using the SCTP multistream property. The multihoming feature is a valuable capability for the redundancy aspect. This feature uses the physical available networks without the application be concerned in a network fail. The chunk feature maximizes the use of the lower network layers by sending much kind of application packets (chunks) into the same network frame. The goal of this paper is to introduce the SCTP protocol and show how it can be used in the CIM and e-manufacturing environment.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.
