Differential Dynamic Programming Approach for Robust-optimal Low-thrust Trajectory Design Considering Uncertainty

Abstract: This paper proposes a robust-optimal trajectory design method for uncertain system to minimize the expected value of objective function. The basic idea is solving Stochastic Differential Dynamic Programming (SDDP), which solve optimal control problem to minimize the expected value of cost-to-go function, with Unscented Transform, which is used to estimate the expected value. Most rece...

Differential Dynamic Programming Approach for Robust-optimal Low-thrust Trajectory Design Considering Uncertainy

This study proposes a fast computation technique to solve robust optimal control based on two techniques: Robust Dynamic Programming [1] and Differential Dynamic Programming [2] to design a low-thrust robust optimal trajectory considering uncertainty to minimize the worst-case objective function. In recent years, low-thrust propulsion systems have been increasingly used in the interplanetary mi...
