Rapid Computation of Optimal Trajectories
IBM Journal of Research and Development, 1967A generalized "indirect" method of solving two-point boundary value problems is discussed in application to the problem of computing optimal trajectories in a vacuum. Improved numerical techniques make the method extremely fast when a good initial estimate of the solution is available, but it also converges, more slowly, from initial estimates that are

Drilling trajectory optimization
IEEE Instrumentation & Measurement Magazine, 2013This is an excellent introduction to contemporary drilling technology. A well is not just a hole in the ground; putting the hole where you want it is no small matter.

Motion planning is a core technology for autonomous driving. It must produce safe, human-like and human-aware trajectories in a wide range of driving scenarios. Whilst much progress has been attained in the perception and localization domains, digital representations of the world are still incomplete.

Abstract : The proliferation of papers published on various aspects of optimum space trajectories has made it desirable to produce a unified treatment of this subject that contains the major results of these papers. This monograph on optimal space trajectories is addressed to this goal.

The power of Mathematica is revealed once more by this chapter. It is focused on certain problems of calculus of variations and optimal control. We show how one can transform a theoretical problem of calculus of variations or optimal control into a numeric one with codes and graphs. In this way, the problem and its results are more intuitive.

Approximate finite-thrust trajectory optimization.
AIAA Journal, 1969Summary: A method which rapidly computes optimum finite-thrust space trajectories is presented. The approach is based on the approximation of the state time history by a polynomial. Differentiation and integration are performed in closed form and the problem is reduced to one of ordinary calculus.

Regularization in optimal trajectory problems.
AIAA Journal, 1968Fig. 3b Oscilloscope trace from the pressure gage in the surface of the 9° cone model. 20^5 Mach reflection theory. There is a kink in the reflected shock wave, downstream from the Mach stem. The kink suggests some further shock reflections in the flow behind the Mach stem. The pressure gage trace corresponding to the 41° indicident angle adds evidence

This thesis investigates optimal trajectory tracking of nonlinear dynamical systems with affine controls. The control task is to enforce the system state to follow a prescribed desired trajectory as closely as possible. The concept of so-called exactly realizable trajectories is proposed.
