The main result in optimal control theory is undoubtedly the Pontryagin’s maximum principle which provides necessary optimality conditions lifting the optimal state trajectory to the contangent space introducing a covector. In this mini-symposium we propose to present new developments of necessary optimality conditions i) for optimal control problems with parameters with applications to problems involving a bi-level structure, ii) for optimal control problems mixing permanent and nonpermanent controls in relation with hybrid optimal control. We also propose to present industrial applications where the resolution of the necessary conditions given by the Pontryagin’s maximum principle is a challenging task and leads to the development of new algorithmic techniques. Two applications are presented: i) low-thrust satellite collision avoidance, ii) the hybrid electric vehicle torque split and gear shift problem.
