A wind turbine is a very complex, non-linear system influenced by a stochastic wind speed variation. The reduced dynamics considered in this work are the rotational degree of freedom of the rotor and the tower for-aft movement. The MPC design is based on a receding horizon policy and a linearised model of the wind turbine. Due to the change of dynamics according to wind speed, several linearisation points must be considered and the control design adjusted accordingly. In practice is very hard to measure the effective wind speed, this quantity will be estimated using measurements from the turbine itself. For this purpose stationary predictive Kalman filter has been used. Stochastic simulations of the wind turbine behaviour with applied frequency weighted model predictive controller are presented. Statistical comparison between frequency weighted MPC, standard MPC and baseline PI controller is shown as well.","PeriodicalId":232418,"journal":{"name":"2013 International Conference on Process Control (PC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132239150","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 combined production of heat and electricity seems to be a good option for a future market. Cogeneration has fewer losses than traditional production, but on the other hand there are some consumption criteria that must be met. The result of this paper is a software library of the significant parts of CHP plants of different types. Firstly there are short introductions to the two main types of units used for low output power (up to approximately 100 kW) - the gas/biogas/diesel/biodiesel engine and gas (micro-)turbine. The next section describes the basic physical and mathematical relations and the final section presents some results.","PeriodicalId":232418,"journal":{"name":"2013 International Conference on Process Control (PC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131897323","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}

Calibration is necessary to adapt the simulation of the model of the manufacturing equipment to real geometric conditions. The article also presents the use of a comparison of two approaches to solve the position control of the physical pendulum. When designing the motion control of mechanical systems it is necessary to describe the dynamics of the system by mathematical model that is equations of motion that describe the response of the system to the action hit of the drive unit. To solve the equations of motion we use mathematical programs, in which regulatory structures such as PID controller are implemented. MATLAB/Simulink is an important representative of these programs.","PeriodicalId":232418,"journal":{"name":"2013 International Conference on Process Control (PC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134509629","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 economic optimization problem comprises two classical optimization criteria, namely minimum time and minimum diluant (solvent) consumption. In order to reflect the varying prices of individual parts of operational cost to the economically optimal process on longer time horizon, we treat the resulting optimization problem as a multi-objective one. We use analytical solution to this problem, obtained by applying Pontryagin's minimum principle, which provides conditions for switching of optimal control structure and for evaluation of economically optimal diluant utilization strategy. The here developed methodology is applied to the examples of UF/DF processes taken from the literature and economical benefits of using such advanced control strategy are discussed.","PeriodicalId":232418,"journal":{"name":"2013 International Conference on Process Control (PC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134078379","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 mathematical analysis for all parts, that is, for all the units of the steam reheater, is presented in the form of ordinary differential equations. The turbine simulation model is based on real process measurements and uses the ARX model.

The identification of a controlled system is based on a biased relay experiment. The identified system is consecutively approximated by a low order transfer function with a time delay. The controller parameters are then computed through the solution of a Diophantine equation in the ring of proper and stable rational functions. Tuning of the controller parameters can be achieved by a pole-placement problem as a desired multiple root of the characteristic closed loop equation. This approach introduces a scalar tuning parameter which can be adjusted by several methods.","PeriodicalId":232418,"journal":{"name":"2013 International Conference on Process Control (PC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124076216","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 airship assumed to be used in applications that consider existence of restricted environment and require the airship to fly few meters above the ground where there is a big possibility of collisions with obstacles. The proposed On-line path planner takes in consideration the detections of the unexpected obstacles, the changes in the environment conditions and the modifications on the mission goals. The On-line path planning has two processes: path recovery which is responsible to produce feasible paths to avoid collisions with obstacles. Path recalculation which is responsible to keeps the route of the airship as optimal as possible according to a certain optimization criteria. The experimental simulation tests of the proposed On-line path planning shows that it success to avoid obstacles and find alternative optimal routes in a reasonable time.","PeriodicalId":232418,"journal":{"name":"2013 International Conference on Process Control (PC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131792799","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}
