De Pinho, Maria Do RosárioSilva, Geraldo Nunes [UNESP]2014-05-272014-05-272010-12-01Proceedings of the IEEE Conference on Decision and Control, p. 7045-7050.0191-2216http://hdl.handle.net/11449/72033We consider free time optimal control problems with pointwise set control constraints u(t) ∈ U(t). Here we derive necessary conditions of optimality for those problem where the set U(t) is defined by equality and inequality control constraints. The main ingredients of our analysis are a well known time transformation and recent results on necessary conditions for mixed state-control constraints. ©2010 IEEE.7045-7050engConstrained optimal control problemsControl constraintMixed state-control constraintsNecessary conditions of optimalityTime-optimal control problemsControlOptimizationTrabalho apresentado em evento10.1109/CDC.2010.5718008Acesso aberto2-s2.0-799531519223638688119433520
