In some cases, the force information measured by wrist force sensor consists of the external force and the undesired inertial force arising from the acceleration of the end-effector. Up to now, il: is still difficult to extract the external force exactly for the insufficiency of acceleration information. A novel six-axis accelerometer in. the type of dual annular membranes structure is presented in this paper. It can simultaneously measure all three linear acceleration components ax, ay, az, and three angular acceleration components ax, ay, az which can be used to extract the external forces. The Finite Element Method (FEM) simulations were carried out to optimize the configuration of strain gauges. The analysis of the rated strains and interference strains indicates that the accelerometer has a low level cross-sensitivity. The characteristic experiment shows that the linearity of the accelerometer is good with minor interference errors. It also reveals that the rated strains and interference strains are in good correspondence with the results from the FEM simulations.","PeriodicalId":375056,"journal":{"name":"2004 International Conference on Intelligent Mechatronics and Automation, 2004.

The abundant real-time data gathering in power system contain the complexity and uncertainty of the system, so mining and fusing a series of universal applicable quantities from these datu to detect system fault and its stability is essential. Combining wavelet analysis, the. modern time-frequency analysis technique, with entropy theory by exploiting their virtues will resolve ;the problem. I n this paper, the feasibility of the wavelet entropy applicution in power system fault detection and distinguish is analyzed, the wavelet entropy concept based on wavelet analysis is defined, the computation methods of the two kinds of wavelet entropies are established, and the application of the wavelet entropy in transmission line fault detection is simulated and analyzed. The modem power system has already stepped into high voltage, large power grid and large generator era, the extensive interconnection of the power system and the adoption of numerous new and,high technology, in addition the introduction of the electricity power market mechanism make systematic complexity higher and higher. All these are nowadays the remarkable characteristics of power system. The big electric network has brought potential danger while bringing enormous interests to users. Some partial problems of the electric network can bring out malignant chain reaction and lead to great systematic accident and power failure by a large scale. Measuring various kinds of faults in the power system in time, classifying fault fast and accurately, setting up a high-efficient fault information measuring and classifying online system of power system, are very essential for dealing with the power system fault, even for preventing the calamities and changes of the power system. Power system itself is an open dynamic system, because of the interference of environment to the motive force characteristic of power system, to measure and classify the fault accurately, and to prevent the accident from further development totally is difficult. Therefore drawing and classifying the characteristic of the fault information have already become the focal point and one of the difficult points of electric power system research. Besides complexity and uncertainty of power system , the non-linearity and time-change in systems exist objectively, so calculating and classifying the fault by routine theory based on mathematics model seem unable to do what one wishes.

U-shape anti-roll tank consists of two tanks partially filled with water with the air spaces connected by a duct and a crossover duct at the tank bottom, and one valve is equipped in air duct to realize optimal stabilizing effect in most cases. In order to control the valve exactly, the natural period of U-shape anti-roll tank must be measured by effective methods. This paper disc\" two mdmb based on model experiment from the point of view of practicability, and shows these methods can be used to measure the natural period of U-shape anti-roll tank exactly. Further study needs to put emphash on validating the stabilizing effect and improving tank design. the stabilizing effect of the U-tank is best in this condition. At other wave periods, the stabilizing effect is much less, and the increase of the roll motion of the ship even occurs at some wave periods. It is well known that the U-tank is equipped with a valve in air duct to realize optimal stabilizing effect in most cases. The most important problem is how to control the valve in different wave periods. One way is to determine optimal time period for closing and opening the valve refemng the natural period of the U-tank. In this paper, the natural period of the U-tank model was measured exactly by two experimental methods, so it becomes possible that the valve can be closed and opened with optimal time period aimed at producing the largest counteracting moment. The key problem realizing optimal control of the U-tank was solved very well.","PeriodicalId":375056,"journal":{"name":"2004 International Conference on Intelligent Mechatronics and Automation, 2004.
