The DC offset in a pure integrator is eliminating using a high-pass filter with fixed time constant. The time constant of programmable low-pass filter is controlled with a synchronous frequency of the induction motor for an integration, considering phase lag and attenuation due to both the hardware low-pass filter and the programmable low-pass filter. The proposed strategy is verified with experiments implemented with a 32-bit TMS320C30 DSP.","PeriodicalId":250552,"journal":{"name":"Proceedings Third Russian-Korean International Symposium on Science and Technology.

Kuznetsov","doi":"10.1109/KORUS.1999.875871","DOIUrl":"https://doi.org/10.1109/KORUS.1999.875871","url":null,"abstract":"This report focuses on the solution of contamination problem on the developing International Space Station. It was demonstrated that the orientation thrusters and the reheling systems are the main contamination sources on the station. Experimental modeling of these real gasdynamic contamination processes was maid. The new concept was formulated and new technical solutions were found aimed to reduction of the total divergence angle of contaminating fractions. This would make possible to almost completely eliminate the Contamination of the Working Module of the International Space Station. Introduction The real investigations on the orbital space station MIR and modeling experiments [1,2] revealed that operation of its orientation thrusters is accompanied with exhaust into space of burned and non-burned (including droplets) particles which go throughout almost the whole sphere (from 0 to 180\" relative the jet axis). The elements of the space station being exposed to the exhaust jet of the orientation thruster undergo the mechanical, physical and chemical impact, which of are, certainly, a negative factor for them. Existence of cold surfaces (even those beyond the stream field) may cause secondary processes of condensation and makes the contamination zone even larger. The radical solution of a problem consists, probably, in refusal of orientation thrusters on chemical fuel and transition to thrusters of other type, for example, electrical on chemical neutral gases with large molecular weight xenon, krypton, argon, fulleren C60 etc. But in this case there is a problem of electrophysical effect of an exhaust plume on construction elements of orbital station. However at the present stage of development of space engineering it is quite expedient to raise the question about elimination (in a limit exception) negative influence of a plume of orientation thrusters on construction elements of orbital station. It is possible to solve this problem by limiting an angle of expansion of contaminating fractions. The engineering solution of this idea consists in the installation on an output part of the nozzle of orientation thruster of special gasdynamical protecting devices. At the same time this gasdynamical protecting devices should not change the parameters of orientation thruster, first of all thrust vector and its value (specific impulse). As far as it is known to the authors, earlier idea of use gasdynamical protecting devices for limitation of an angle of expansion of contaminating fractions and, accordingly, elimination of contamination of orbital station was not considered and was not realized. This paper is devoted mainly to the experimental solution of the shown idea. 0-7803-5729-9/99/$10.00","PeriodicalId":250552,"journal":{"name":"Proceedings Third Russian-Korean International Symposium on Science and Technology.

Introduction The unsuitableness for existing type of economical conduct of enterprises to the conditions of being trains-formed economy is the cries aggravating Factor. The enterprises of industries were not entirely able to adapt themselves to the started up situation. The penning-competent industrialeconomic systems aimed to h e final result have to come to replace traditional structures and methods organizing. All this dictates the Need of changing the strategy of organization for the production activity of enterprises, where are taken into account the intensively expanding reasons to show up the risk Situations. The objective estimation of the given situation on the market, the formation of adequate control (handling) system require the analysis and the evaluation of production risk, imply mastering the risk heuristic, the capability to take and to carry out non-typical decisions, to change in flexible way the strategy and the tactics of activity in the production on the part of the enterprise administration. . In the final analysis the country competitiveness depends on the ability of a certain enterprise to produce competitive product. Since Russian enterprises do not possess the real international competitiveness in the sphere of industrial goods quality, they could successfully compete on the world market mainly at the expense of the export production price. However the home-produced goods competitiveness on the external market is difficult to count on because material factors are rather expensive (Table 2). 0-7803-5729-9/99/$10.00","PeriodicalId":250552,"journal":{"name":"Proceedings Third Russian-Korean International Symposium on Science and Technology.

The influence of types of the shape functions in RVM for the analysis of the deflection and stress distributions on rectangular diaphragms is studied for 1/spl les/m/spl les/5 where size ratio m=a/b. The comparison of calculated results of the deflection and stress distribution by RVM with those by FEM shows little difference for m=1, but for m>2 all kinds of the shape functions give errors, for example with Hermite polynomials, such as a saddle form on deflection distribution. For m/spl les/2 the difference by the two methods is less than 10%. For the evaluation of displacement of piezoresistors at the most interesting points on the diaphragm, the RVM shows that the deflection and stress distribution can be estimated easily and accurately.","PeriodicalId":250552,"journal":{"name":"Proceedings Third Russian-Korean International Symposium on Science and Technology.
