In this work, we study both minimal and maximal blowup time controls for some ordinary differential equations. The existence and Pontryagin’s maximum principle for these problems are derived. As a key preliminary to prove our main results, due to certain monotonicity of the controlled systems, “the initial period optimality” for an optimal triplet is built up. This property reduces our blowup time optimal control problems (where the target set is outside of the state space) to the classical ones (where the target sets are in state spaces).
