摘要：This article studies a time optimal control problem ( P ) for some switching controlled systems. We first prove the existence of time optimal controls to the problem ( P ) . Then, we derive the bang-bang property for time optimal controls to this problem, through utilizing the Pontryagin maximum principle. AMS Classification: 49K20; 35J65.
