Low-Thrust Lyapunov to Lyapunov and Halo to Halo with $L^2$-Minimization [PDF]
, 2016 In this work, we develop a new method to design energy minimum low-thrust missions (L2-minimization). In the Circular Restricted Three Body Problem, the knowledge of invariant manifolds helps us initialize an indirect method solving a transfer mission ...

The Direct Shooting Method is a Complete Method
, 2021 The direct shooting method is a classic approach for the solution of Optimal Control Problems (OCPs). It parameterizes the control variables and transforms the OCP to the Nonlinear Programming (NLP) problem to solve. This method is easy to use and it often introduces less parameters compared with all-variable parameterization method like the Pseudo ...

Calculation of nonlinear vibrations of piecewise-linear systems using the shooting method
Vietnam Journal of Mechanics, 2012 In this paper, an explicit formulation of the shooting scheme for computation of multiple periodic attractors of a harmonically excited oscillator which is asymmetric with both stiffness and viscous damping piecewise linearities is derived.

Shooting continuous Runge–Kutta method for delay optimal control problems [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2022 In this paper, we present an efficient method to solve linear time-delay optimal control problems with a quadratic cost function. In this regard, first, by employing the Pontryagin maximum principle to time-delay systems, the original problem is converted

Application of Global Methods in Parallel Shooting [PDF]
SIAM Journal on Numerical Analysis, 1993 A new divide-and-conquer method is proposed to employ a coarse grid discretization like multiple shooting does, but to solve the local problems in a ``boundary value problem-way''. A sophisticated error control is developed to combine local and global convergence of the Newton updating. An implementation, called the unbiased multiple shooting algorithm
