Elongation of Curvature-Bounded Path
Zheng Chen, Kun Wang, Yang Lu
The paper is concerned with elongating the shortest curvature-bounded path between two oriented points to an expected length. The elongation of curvature-bounded paths to an expect…
Time-Optimal Guidance for Intercepting Moving Targets with Impact-Angle Constraints
Yuan Zheng, Zheng Chen
The minimum-time path for intercepting a moving target with a prescribed impact angle is studied in the paper. The candidate paths from Pontryagin's maximum principle are analyzed,…
Time-Optimal Guidance to Intercept Moving Targets by Dubins Vehicles
Yuan Zheng, Xueming Shao, Zheng Chen +1
This paper is concerned with a Minimum-Time Intercept Problem (MTIP), for which a Dubins vehicle is guided from a position with a prescribed initial orientation angle to intercept…
Optimality conditions applied to free-time multi-burn optimal orbital transfers
Zheng Chen
While the Pontryagin Maximum Principle can be used to calculate candidate extremals for optimal orbital transfer problems, these candidates cannot be guaranteed to be at least loca…
-optimality conditions for circular restricted three-body problems
Zheng Chen
In this paper, the L1-minimization for the translational motion of a spacecraft in a circular restricted three-body problem (CRTBP) is considered. Necessary con- ditions are derive…
Neighboring Optimal Guidance for Low-Thrust Multi-Burn Orbital Transfers
Zheng Chen
This paper presents a novel neighboring extremal approach to establish the neighboring optimal guidance (NOG) strategy for fixed-time low-thrust multi-burn orbital transfer problem…
-Minimization for Mechanical Systems
Zheng Chen, Jean-Baptiste Caillau, Yacine Chitour
Second order systems whose drift is defined by the gradient of a given potential are considered, and minimization of the -norm of the control is addressed. An analysis of the…
Controllability of Keplerian Motion with Low-Thrust Control Systems
Zheng Chen, Yacine Chitour
In this paper, we present the controllability properties of Keplerian motion controlled by low-thrust control systems. The low-thrust control system, compared with high or even imp…
