The algorithm, named adaptive multiple shooting, automatically generates a problem-dependent parameterization of the control profiles: Starting from an initially coarse parameterization, the control grid is refined iteratively using a wavelet analysis of the previously obtained optimal solution. Additional grid points are only inserted where required and redundant grid points are eliminated. Hence, the algorithm minimizes the number of grid points required to obtain accurate optimal control trajectories.First, we demonstrate the superiority of adaptive grid refinement over an equidistant discretization for the Williams–Otto semi-batch reactor employing multiple and single shooting. Here, the accuracy is checked using an optimal solution obtained by an indirect optimization approach. Second, we successfully demonstrate the efficiency of adaptive grid refinement compared to an equidistant discretization employing multiple shooting to a dynamically unstable HIPS (high impact polystyrene) polymerization reactor. 000826313 536__ $$0G:(DE-HGF)POF3-899$$a899 - ohne Topic (POF3-899)$$cPOF3-899$$fPOF III$$x0 000826313 588__ $$aDataset connected to CrossRef 000826313 7001_ $$0P:(DE-Juel1)162219$$aMarquardt, Wolfgang$$b1$$eCorresponding author 000826313 773__ $$0PERI:(DE-600)1499971-7$$a10.1016/j.compchemeng.2013.09.017$$gVol. 60, p. 242 - 259$$p242 - 259$$tComputers & chemical engineering$$v60$$x0098-1354$$y2014 000826313 8564_ $$uhttps://juser.fz-juelich.de/record/826313/files/1-s2.0-S0098135413002986-main.pdf$$yRestricted 000826313 8564_ $$uhttps://juser.fz-juelich.de/record/826313/files/1-s2.0-S0098135413002986-main.gif?subformat=icon$$xicon$$yRestricted 000826313 8564_ $$uhttps://juser.fz-juelich.de/record/826313/files/1-s2.0-S0098135413002986-main.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000826313 8564_ $$uhttps://juser.fz-juelich.de/record/826313/files/1-s2.0-S0098135413002986-main.jpg?subformat=icon-180$$xicon-180$$yRestricted 000826313 8564_ $$uhttps://juser.fz-juelich.de/record/826313/files/1-s2.0-S0098135413002986-main.jpg?subformat=icon-640$$xicon-640$$yRestricted 000826313 8564_ $$uhttps://juser.fz-juelich.de/record/826313/files/1-s2.0-S0098135413002986-main.pdf?subformat=pdfa$$xpdfa$$yRestricted 000826313 909CO $$ooai:juser.fz-juelich.de:826313$$pVDB 000826313 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000826313 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCOMPUT CHEM ENG : 2015 000826313 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000826313 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000826313 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000826313 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000826313 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000826313 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000826313 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000826313 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000826313 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000826313 9141_ $$y2016 000826313 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)162219$$aForschungszentrum Jülich$$b1$$kFZJ 000826313 9131_ $$0G:(DE-HGF)POF3-899$$1G:(DE-HGF)POF3-890$$2G:(DE-HGF)POF3-800$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bProgrammungebundene Forschung$$lohne Programm$$vohne Topic$$x0 000826313 9201_ $$0I:(DE-Juel1)VS-V-20090406$$kVS-V$$lVorstandsbereich Wissenschaft, Außenbeziehungen$$x0 000826313 9201_ $$0I:(DE-Juel1)GRS-20100316$$kGRS Jülich ; German Research School for Simulation Sciences$$lGRS$$x1 000826313 980__ $$ajournal 000826313 980__ $$aVDB 000826313 980__ $$aI:(DE-Juel1)VS-V-20090406 000826313 980__ $$aI:(DE-Juel1)GRS-20100316 000826313 980__ $$aUNRESTRICTED
