This fast, under-actuated nonlinear mechatronic system apparently poses a challenging benchmark problem that might benefit from a nonlinear optimization scheme. To overcome the related computational difficulties we make use of the ACADO Code Generation tool allowing to export a highly efficient Gauss-Newton real-time iteration algorithm tailored to the nonlinear model dynamics while respecting imposed constraints. We show simulation results illustrating the overall control performance of the closed-loop system as well as the advantages of the nonlinear MHE-based NMPC scheme.","PeriodicalId":173529,"journal":{"name":"2015 20th International Conference on Process Control (PC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122803559","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}

For this task efficient simulation and optimization tools of the MATLAB system are fruitfully exploited. The control system design is based on the algebraic approach resulting in the pole-placement problem to be solved. This task is addressed numerically using the standard MATLAB functions for nonlinear constrained optimization to meet both the constraints on the manipulated variable and robustness of the resultant closed-loop. Certain control quality criteria and a procedure are introduced for this purpose. The suggested algorithm is illustrated on the AMIRA DR300 servo-system controlled both in robust sense and with limited control action. Presented results show applicability of the suggested approach.","PeriodicalId":173529,"journal":{"name":"2015 20th International Conference on Process Control (PC)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114209854","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}

For complex shaped trajectories there are often many high resolution coincident points generated from CAD/CAM systems or trajectory generators. The preprocessing (refining) is necessary for proceeding these points to the manipulator control system. Two interpolation methods are discussed: Line interpolation with polynomial blending and new proposed method Cubic spline interpolation with recalculated feed rate. Second introduced method describes how to interpolate the coincident points and compute the feed rate of the interpolation in order to reduce undesirable peaks in acceleration and ensure demanded position, velocity and acceleration profile along the trajectory. The new interpolation algorithm was implemented to the trajectory generator for complex pipe weld inspection robot. Experimental measurements made on control system of real prototype are finally presented for evaluation of proposed method performance.","PeriodicalId":173529,"journal":{"name":"2015 20th International Conference on Process Control (PC)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115616089","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 task was to suite chemical reactor dimensions to a specific process in such way, so that the process could run most effectively. An objective function which included also the reactor mathematical model was defined. The objective function was than modified to find even better results and necessary limitations and also penalizations were used to improve the dimensions searching. An evolutionary approach represented by the Self-Organizing Migrating Algorithm (SOMA) was used to minimize the defined function. Results obtained from simulations with the newly found dimensions were compared with original dimensions ones. The results showed feasibility of the dimensions design for a concrete case, the newly designed reactor embodied better performance. At the end, the possibility of the mathematical model used for the simulation refinement is mentioned.","PeriodicalId":173529,"journal":{"name":"2015 20th International Conference on Process Control (PC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127856497","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}
