摘 要：
In this paper, we propose a unified stochastic optimal control framework that bridges time-optimal control problems and classical stochastic optimal control problems. Unlike traditional deterministic free-time optimal control formulations, our framework incorporates a generalized stochastic control structure under minimum-time constraints, where the minimum-time condition characterizes the earliest achievable moment for reaching a target state in expectation, and the terminal time becomes an endogenous control-dependent variable. The main contributions of this study are: Derivation of an extended stochastic maximum principle for the proposed model; Clarification of the connections between mean-field optimal control and time-optimal control problems.
