{"title":"Virtual collocation of sensors and actuators for a flexible rotor supported by active magnetic bearings","authors":"Z. Gosiewski, Z. Kulesza","doi":"10.1109/CARPATHIANCC.2013.6560518","DOIUrl":"https://doi.org/10.1109/CARPATHIANCC.2013.6560518","url":null,"abstract":"Local vibration control systems of mechanical structures can be collocated or non-collocated. If a sensor is placed at the same location as an input force, i.e. when all input forces have the distinguishable influence on measurement signals, the system is said to be collocated. When forces act not at locations of sensors, the system is non-collocated. In many real life applications it is not always possible to collocate the vibration control actuator at the location of interest. As an example, an active magnetic bearing (AMB) can be considered, for which eddy current sensors are used to measure shaft displacements. It is obvious that sensors cannot be placed exactly at locations of magnetic coils of the AMB. The shaft segment of a given diameter and some distance between sensors and the rest of the magnetic circuit is required for the proper operation of the AMB. Therefore it is not possible to collocate sensors and actuators in the AMB. Non-collocation complicates the control problem because the dynamics of the structure between the control actuator and the sensor disturbs the performance of the vibration control system. It has been proved, that non-collocated systems have non-minimum-phase zeros at the right half-plane. These zeros decrease the robustness of the control system, increasing its sensitivity to the parameter variation. Furthermore, if these zeros occur within the operating range, the system may become unstable. Non-collocation effects on the stability of the vibration control system can be suppressed by several ways. Phase shifting, time delay or passive vibration absorber methods have been employed in the past. However, none of these methods ensures the required stability margins, wide operational bandwidth, nor good performance. The present paper recommends the virtual (recalculated) collocation. The idea is to calculate displacements at actuator locations given displacements at sensor locations, or to calculate control forces at actuator locations given displacements measured at sensor locations. The paper discusses the former method, as it is a common practice to design local control loops rather than global ones. The approach is illustrated with numerical simulation results of the flexible rotor supported by AMBs and controlled with four PID controllers. The finite element (FE) model of the rotor is developed and transformed to the state-space. The FE model is reduced by the modal truncation technique. Then, an observer for the reduced system is developed. This way shaft displacements at any discretization node along the shaft axis can be simply estimated an introduced to PID controllers. Calculation results demonstrate a good performance of collocated PID control systems, conurming the potential of the method and giving a rationale for its further development.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893905","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}

In the introduction of a contribution are analyzed the processes in a field of the processing of raw materials in which an important role is the process of heat transfer by conduction. There is listed a review of the formulation and solution of the Fourier equation of heat conduction without heat source in the form of partial differential equations of integer and fractional order is listed. The experimental methods for the measurement of thermal diffusivity are also described in the introduction. In the next section is described the mathematical model of one-dimensional heat conduction with the initial and boundary conditions. The principles of implicit and explicit numerical method of solution of partial differential equation describing one-dimensional heat conduction are described. The one-dimensional mathematical model of heat conduction for various initial and boundary conditions of the first and second kind was implemented in MATLAB environment in the form of separate m-functions for implicit and explicit method. The description of the laboratory equipment HT10XC and its module HT11C which is used to measure the thermal conductivity is also listed in the article. The experimental measurements were carried out on the laboratory facility, which is a physical model of heat conduction process. The measurement results compared with the results of simulations of mathematical model are presented in the paper. At the conclusion of the contribution is a proposal for a method of measurement of thermal diffusivity. The method results from experimental measurement of the thermal conductivity on the laboratory facility HT10XC and subsequent realization of simulations on the mathematical model in order to identify the parameter of the model that represents the thermal diffusivity of the measured samples. On the basis of the measured value of thermal diffusivity and its definition can be estimated the specific heat capacity of the measured samples.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131466996","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 proposed controller takes advantage of an appropriately designed sliding hyperplane, which ensures the closed-loop system stability and finite-time error convergence to zero. Moreover, the proposed controller ensures full utilization of the bottleneck link available bandwidth, guarantees bounded transmission rates, and eliminates the risk of buffer overflow in the bottleneck node. The proposed controller is designed using the concept of the reaching law, which helps to limit data transmission rates in the network.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128215408","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}

They are heavily dusted and contain combustible components. The basic element in its treatment system is a post combustion chamber localized directly behind the technological furnace. This chamber permits combusting combustible components and precooling the gases with the aid of cooling water and air. Analysis of the processes occurring in the post combustion chamber is important to reduce the system energy consumption. It requires elaborating a mathematical model which describes the most significant physical and chemical phenomena accompanying the post combustion and cooling. The paper presents a mathematical model of the post combustion and cooling the process gases from an electric furnace in a copper plant. This model was elaborated by means of the CFD (Computational Fluid Dynamics) software (Gambit and Fluent). The k-ε Realizable model of turbulence, a single-stage carbon monoxide combustion model and the DO (Discrete Ordinates) model of radiation were used to build it. Numerical simulations were carried out on the basis of the elaborated model for the maximal mass flow of the process gases form the electric furnace. Exemplary calculation results are presented.","PeriodicalId":373601,"journal":{"name":"Proceedings of the 14th International Carpathian Control Conference (ICCC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132951694","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}

In the first part of the paper, the LuGre model for the RD-1097-01 MR damper is identified based on the MR damper force measurements under sine excitation and constant currents.
