Trajectory control laws based on neural ordinary differential equations (ODEs) were proposed by the authors in a previous study. This paper extends the trajectory control laws by integrating a reservoir computing architecture. The addition can significantly reduce the number of design parameters to be optimized and thus the computational cost of training while maintaining the structure of the control laws. This enhancement allows general-purpose nonlinear optimization algorithms to be used, extending the application of neural ODEs to operation design optimization beyond the design of control laws. This study verifies the effectiveness of the proposed framework by constructing a control law to achieve the target conditions for a rendezvous operation in a low Earth orbit. Multi-objective design taking advantage of reservoir computing is demonstrated by assessing the Pareto optimal front with respect to orbital transfer time and control accuracy.
