The results obtained in the present paper demonstrate that their solution of the linearization problem for a second-order ordinary differential equation Abstract : A generalized Sundman transformation dt = crnds for exponent n 1 may be used to accelerate the numerical computation of high-eccentricity orbits, by transforming time t to a new independent variable s. Once transformed, the integration in uniform steps of s effectively gives analytic step variation in t with larger time steps at apogee transformation, a generalized Sundman transformation (Ref. 2), allows one to use any numerical integration method in the independent variable s, which is thus called s-integration. Conventional time integration, by contrast, is called t-integration.

However, this consideration … of a generalized Sundman transformation, or s-integration (Ref. 2), which may be considered an analytical step regulation. In s-integration the independent variable is changed from time, t, to an angle s, which spreads the integration steps more evenly about an elliptical orbit. A Sundman transformation is a reparametrization of the temporal variable that was first used as part of an analytic solution to the three-body problem.

Previous efforts addressed the challenge of low-thrust many-revolution trajectory optimization by applying a Sundman transformation to change the independent variable of the spacecraft equations of motion to an orbit anomaly and performing the optimization with differential dynamic programming (DDP). transformation, a generalized Sundman transformation (Ref. 2), allows one to use any numerical integration method in the independent variable s, which is thus called s-integration. Conventional time integration, by contrast, is called t-integration.

In the literature, the generalized Sundman transformation has been used for obtaining necessary and sufficient conditions for a single second- and third-order ordinary differential equation to be equivalent to a linear equation in the Laguerre form. a Sundman transformation. The Sundman transformation, whereby a new temporal variable is introduced, results in a system for which solutions exist globally. In addition, it provides a means for simultaneously proving blow-up and ﬁnding analytical estimates of blow-up times. 1. Introduction. Problems for which solutions develop ﬁnite-time

2019-12-01 Abstract : A generalized Sundman transformation dt = crnds for exponent n 1 may be used to accelerate the numerical computation of high-eccentricity orbits, by transforming time t to a new independent variable s. Once transformed, the integration in uniform steps of s effectively gives analytic step variation in t with larger time steps at apogee than at perigee, making errors at each point GENERALIZED SUNDMAN TRANSFORMATIONS Transformation equation Sundman (Ref. 3) and Levi-Civita (Ref. 4), in attempting to solve the restricted problem of three bodies, introduced the transformation of the independent variable dt = crds, (1) with c constant for the two-body orbit, because this transformation regularizes, and in fact linearizes, 2010-06-15 2010-07-01 In this article, the linearization problem of fifth-order ordinary differential equation is presented by using the generalized Sundman transformation. The necessary and sufficient conditions which allow the nonlinear fifth-order ordinary differential equation to be transformed to the simplest linear equation are found. There is only one case in the part of sufficient conditions which is generalized Sundman transformations it is not sufficient to use the Laguerre form. In this paper, we demonstrate that the solution of the linearization problem via the genera-lized Sundman transformation of second-order ordinary differential equations given in … Let be a generalized Sundman transformation and let us define the generalized Sundman anomaly as the regularized value of given by where if , for all , and .
