報(bào)告摘要:
In this talk, we consider optimal control problems involving switched time-delay systems with time-dependent switching conditions as well as with state-dependent switching conditions. For these two classes of optimal control problems, we first show that the system state variations with respect to the system parameters and switching instants can be expressed as the solutions of a set of auxiliary switched systems at almost all time points. On this basis, we develop gradient-based optimization algorithms to determine the optimal switching controls. Finally, we validate the proposed algorithms by solving example problems including one real-world optimal control problem arising in the production of 1,3-propanediol.
