This unit is a part of the gas turbine cogeneration plant (GT CP). The problem of modeling the phenomena of rotor dynamics is solved with full consideration of controlled electromagnetic processes in active magnetic bearing (AMB) circuits. In order to analyze them, the method of contour flows similar to the method of contour currents for the analysis of electrical circuits is used. To describe the electromagnetic circuits of the AMB, detailed substitution schemes are introduced which take into account almost all the elements of the magnetic circuit (air gaps, sections of magnetic cores, grooves with windings, coils and other parts). Description of the considered mechatronic system requires constructing a mathematical model on the basis of application of the magnetomechanical Lagrange-Maxwell equations. The resulting system of differential equations relates to the generalized mechanical coordinates and flux linkages of the electric circuits of the AMB coils. The calculation results have the form of Cambell diagrams and amplitude-frequency characteristics of rotating rotors. Verification of the proposed approach to the modeling of dynamic phenomena in a rotary mechatronic system involves comparison with known calculation data. A comparative analysis reveals the advantages of the proposed approach for numerical simulation of the dynamics of rotors of controlled mechatronic systems and industrial electromechanical machines.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"121 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123178102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The filter consists of a voltage source inverter on fully controlled switches, capacitor storage, and a first-order three-phase RL filter. The decomposition of the object of study according to the rates of motion of the dynamic system was performed. The fast subsystem is a circuit of compensation current control, the slow subsystem performs stabilization of the capacitor voltage. A double twisting algorithm to control the DC voltage is used. In it, to calculate the “operator variable”, in addition to the error of the capacitor storage voltage to increase the speed is also used its derivative. A two-dimensional sliding manifold to generate the compensating current is used. Each component of this surface is a linear combination of components of two-dimensional vectors. The first vector is the current error of the RL filter, the coordinates of the second are locally equivalent to the derivative of this error. The calculation of the instantaneous value of both components of the second vector by entering the second order sliding mode was forced. A simulation model is developed and the results of simulation are analyzed. A comparison of the proposed strategy with the traditional PI-regulation by the criteria of the duration of the transition process and the coefficient of harmonic distortions in the current consumed from the network is made.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115900570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
