About

Optimal control is a mathematical framework for computing input sequences or feedback policies that drive a dynamical system from an initial state to a desired goal while minimizing a cost function — such as time, energy, or control effort — subject to physical and operational constraints. In robotics and AI, it underpins a wide range of capabilities: planning time-optimal trajectories for manipulators, generating stable locomotion for humanoids, and synthesizing motion plans that respect actuator limits and safety constraints. Practical computational approaches include direct collocation, multiple shooting, and differential dynamic programming, supported by tools like CasADi. Optimal control also connects naturally to model predictive control, which re-solves the optimization online to handle disturbances, and to reinforcement learning, where it informs policy search and inverse cost-learning methods. Its importance lies in providing principled, mathematically rigorous tools for generating high-performance robot behavior — enabling systems to act efficiently and safely in complex, constrained environments while offering interpretable guarantees that purely data-driven methods often lack.
