Active yaw stabilization for passenger vehicles, following driver yaw rate commands with steer-by-wire and rear break force distribution, is discussed. The problem is solved via a decomposition of the vehicle equations of motion into a static, scheduled tyre characteristics map, and an affine Linear Parameter Varying (LPV) plant. control is provided via a cascade connection of scheduled inverse tyre characteristics and an LPV controller, handling both the nonlinear dynamics an the non-affine tyre characteristics. Excellent tracking results are demonstrated with a high fidelity simulation even in the presence of noise and uncertainty. © 2009 EUCA.

Applying hyperbolic wavelet constructions in the identification of signals and systems

IFAC Proceedings Volumes 2009年第10期42卷 1334-1339页

This paper is devoted to the construction of wavelet-type transforms with the purpose to represent functions belonging to the Hardy-space H 2 . The concept of the affine wavelet-transform defined in the space L 2 is extended to the Hardy space H 2 on the basis of the Blaschke group. A discrete hyperbolic wavelet scheme is also constructed that results in computable forms. The wavelet construction obtained possesses good localization properties with respect to functions in H 2 , hence forms an adequate tool for signal and system identification purposes.

The paper presents a joint state and unmeasured input estimation technique for a special class of nonlinear second order macroscopic traffic model. The freeway traffic system is transformed into a quasi and affine approximate Lin- ear Parameter Varying (LPV) form. Observer design technique is formulated using off-line optimization problem subjected to Linear Matrix Inequality (LMI) conditions, considering uncertain scheduling parameters. Furthermore, locally designed state estimators are interconnected to cover multiple freeway sections. The elaborated method is validated using real traffic measurements. © 2009 EUCA.

Quantitative analysis and detection of abnormalities for electroencephalogram (EEG) recordings during evoked activities are essential for clinical diagnosis on neurological disorders. However, the process of interpreting EEG is time consuming and requires experienced electroencephalographers (EEGers). In this study, a method of automatic EEG interpretation during hyperventilation was proposed. The purpose is to provide a quantitative interpretation of EEG which is able to conform to EEGers' visual inspection. The final integrated results of automatic interpretation were compared with EEGers' evaluation, and showed high consistence. © 2009 SICE.

Electrocardiogram (EKG) and Electroencephalogram (EEG) are widely used for kinds of disorders detection. In case of EKG, RR interval series is used for heart rate variability (HRV) analysis, which is a reliable reflection of status of autonomic nervous system. HRV is a function of both physical and mental activity. In order to analyze the influence of metal stress on HRV, EKG signals including information of physical activities should be removed. In case of EEG, the major artifacts are induced by electromyogram (EMG) and electrooculogram (EOG). In order to analyze the influence of metal stress on EEG, the signals which include information of body movement should be removed. In this paper, we present a method to classify EEG and EKG signals, based on body movement estimation and artifacts detection. Long time recording are divided into segments and classified. The results indicate that the data classification method purposed in this paper is effective, and body movement is important for analyzing EKG and EEG.

In this study, the multivariate probability distribution was investigated to develop the expert knowledge-based automatic sleep stage determination technique. The ultimate purpose is to develop adaptive automatic sleep stage determination algorithm for clinical practice. Gaussian distribution was adopted to realize automatic parameter selection while Cauchy distribution was adopted to estimate the parameter distribution. The different usage of multivariate probability distribution of Gaussian and Cauchy distribution presented effectiveness for automatic sleep stage determination.

Ensuring system stability in medium-voltage DC (MVDC) integrated power systems (IPS) is a key issue, due to the presence of many shipboard electric users fed by constant power load (CPL) converters. This paper presents an innovative control system aimed at utilizing alternators, connected to the IPS through controlled AC-DC interface converters, to improve MVDC stable voltage control. Such system is designed to control, for each shipboard generator, the AC machine voltage, the prime mover speed and the interface converter, in an integrated way. Technological aspects and control principle scheme of this system will be presented in the paper, with particular reference to the issue of DC-link voltage stability. This system is expected to bring advantages in terms of MVDC IPS integration, stable parallel operation of generators and loads, safe exploitation of alternators capability as a source of stabilizing power.

This paper presents a patent-pending device capable of recording and supervising the urine output of a critical care patient. The device is based on a high precision scale that measures the weight of a commercial urine meter. To isolate the device from the patient's movements, and to guarantee that the urine flows properly through the various tubes of the urine meter, we have designed a support frame made up of Bosch profiles. The scale's readings are captured by an electronic unit and sent to a PC via Bluetooth. A Java application running on the PC records them and supervises the therapeutic goals that the healthcare staff has established for the urine output, and warns of any deviation from these goals. This device does not break the sterility of the commercial urine meter and is easy to build with readily available components. Therefore, this solution is ideal to conduct a series of clinical studies based on a more continuous and accurate monitoring of urine output throughout the stay of a patient in a critical care unit.
