Project Title:

Desensitized Optimal Guidance of

Uncertain Systems

Technical Abstract (Limit 200 words)

It is proposed to develop a trajectory optimization

software package that enables the simultaneous

optimization of a user-specified cost criterion along

with reducing the sensitivity of the resulting

trajectory with respect to modeling errors, external

perturbations, etc. Such insensitivity is a highly

desirable feature for any MDO component or

systems analysis tool. In addition, trajectory

optimization with reduced sensitivity has been long

sought as a stand-alone tool. Specifically, the

project objectives are to extend the existing theory,

which has recently been introduced by the PI, to

enable the treatment of problems with free final

time, control constraints, and state constraints, and

to test ideas for a fast and efficient numerical

implementation scheme. It is proposed to achieve

these objectives through analytical derivations and

through numerical testing and verification. It is

anticipated that the theoretical ground work will be

developed for an easy-to-use desensitized optimal

control software package. The expected NASA

applications include practically all areas of today's

optimal control applications, such as launch vehicle

guidance, aeroassisted orbital transfers,

interplanetary space flight, rocket landing, etc.

Potential Commercial Applications (Limit 200 words)

Direct commercial markets for the software

developed in Phase II: All industries requiring

optimal control of uncertain or externally perturbed

systems, such as aircraft/spacecraft/rocket/missile

guidance, robotics, chemical process control and

optimization, industrial and civil engineering design,

and the control of economic systems. Indirect

commercial potential: Customization of the Phase II

software, consulting, and application of the

developed technology to non-linear robustness

problems.
