The developed control system is based on the principles of the model predictive control. It is intended to replace one part of the existing classical control system that is based on gain scheduled PID controllers. The paper starts with a short description of the controlled plant and then it continues with the description of the predictive controller and its integration into the structure of the existing control system. The main focus is on the results of the functionality tests. The preliminary results hitherto achieved demonstrate the capability of the developed control system and its application potential. However, at the same time, they also show that extensive simulation testing of a controller for such a complex system does not necessarily guarantee perfect control performance and several modifications of the controller will be needed to make it really applicable.","PeriodicalId":377619,"journal":{"name":"2017 21st International Conference on Process Control (PC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132651424","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 results are based on the simplest possible single-track model. Effects of variations in the physical parameters — mass, the moment of inertia, tire priorities, vehicle geometry — on the response times, damping ratios, natural frequencies and other dynamical characteristics are presented and confronted with intuitive and “common sense” expectations and with real-life experience of race car drivers and constructors. We believe that such a report is quite unique and useful by itself: we are not aware of any similar existing report which would provide this systems- and-controls viewpoint on the vehicle dynamics phenomena. In addition, future plans are to apply modern systematic model-based control design approaches to come up with active dynamics modifications solutions — using for instance torque vectoring — surpassing current approaches based mainly on mechanical redesigns and, to some extent, simplest possible local feedback controllers.","PeriodicalId":377619,"journal":{"name":"2017 21st International Conference on Process Control (PC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133412283","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 authors of this paper have faced two problems: the need to determine the delay in total and the need to check whether it varies in time or not. Therefore, the hereby described device was designed.

The chosen case study is given by the ammonia synthesis reactor. Through the application of economic NMPC, it is possible to move the operating point close to the unstable region, corresponding to a 12% increase in the extent of reaction with nominal operations conditions. As a further advantage, the increased conversion of ammonia corresponds to a higher outlet temperature of the system which can be utilized to produce high and medium pressure steam. The proposed economic NMPC is able to adjust in the case of disturbances fast to the new optimal conditions and maintains the productivity of the reactor without engaging into limit-cycle behaviour or extinction of the reactor.","PeriodicalId":377619,"journal":{"name":"2017 21st International Conference on Process Control (PC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114163159","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}

Standard sensors are built upon ceramic base equipped with electrodes and heating or tempering elements. Here at Department of Physics and Measurements a transition to a KBI2 platform made by Tesla Blatna is being conducted. This particular model was chosen because at this time it is the only available one. Main purpose of this paper is mapping its properties, especially the homogeneity of temperature of the chip and overall its dynamic thermal properties. This platform was connected into the heating circuit and readouts of its internal temperature sensor (Ptiooo) were evaluated, the temperature was also observed using an thermal imager FLIR T 400 with a macro flyleaf. Calibration of thermal camera is also discussed as well, as determination of each area emissivity. The main result is description of temperature layout all over the chip of the platform and its step responses measured out of thermographical videos taken when the heating was switched on. These data can be further used as base for temperature regulation circuits design. Also quantification of uncertainties of the internal temperature sensor and temperature gradients, which cannot be neglected during sensor layer evaluation, is based upon these data. In the acquired data, symmetrical temperature layout by longitudinal axis is observed. Problems are seen in gradient over the chips length, for operating temperature 300 °C can this difference reach up to 100 °C.","PeriodicalId":377619,"journal":{"name":"2017 21st International Conference on Process Control (PC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126847001","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}

By applying water on a plate and chilling it under sub-zero temperatures the resulting ice structure is able to fix workpieces form-fitted, ensuring proper holding and clamping forces for upcoming machining operations. For this purpose a number of thermoelectric coolers (TECs) need to be controlled such that a homogeneous temperature profile on the clamping plate is guaranteed as well as the prevention of thawing, especially if external thermal disturbances occur due to machining processes like drilling, turning or milling. To face these challenges a robust controller is designed based on the Lyapunov Theory, proving its asymptomatic stability by means of two sliding surfaces. A clamping system consisting of two TECs, an aluminium clamping plate and a heat sink with forced convection is chosen for simulation purposes. This paper shows the model of such a system with corresponding controller design as well as the simulation results of the control strategy.","PeriodicalId":377619,"journal":{"name":"2017 21st International Conference on Process Control (PC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133258204","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}
