Even earlier, in a likewise pivotal 1971 IEEE Transactions on Automatic Control paper, he investigated infinite-horizon least-squares optimal control and the algebraic Riccati equation from a dissipativity point of view. This note revisits infinite-horizon optimal control leveraging strict dissipativity. We discuss the interplay between dissipativity and stability properties in continuous-time infinite-horizon problems without assuming linear dynamics or quadratic cost functions. Finally, we compare our recent results from Faulwasser and Kellett (2021) to the original findings of Willems (1971).en2405-89632022304954IFACDissipativityOptimal ControlStabilityTransversality ConditionsTurnpikesNatural Resources, Energy and EnvironmentEngineering and Applied OperationsConference Paper10.1016/j.ifacol.2022.11.027Conference Paper
