How does Pontryagin's Maximum Principle relate to the process of determining optimal controls in continuous-time systems?
Pontryagin's Maximum Principle is crucial for establishing necessary conditions that an optimal control must satisfy in continuous-time systems. It connects the dynamics of the system, represented through state equations, with the objective function through the Hamiltonian. By analyzing the Hamiltonian, one can identify the controls that maximize or minimize this function at each moment, leading to an optimal trajectory over time.
