Multi-purpose economic optimal experiment design applied to model based optimal control

Nonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot

This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...

Economic-based Distributed Optimal Design

Spacecraft and launch systems are examples of complex products which require a careful balance between competing concerns, such as performance, weight, and reliability, to serve their mission. Complexity requires design by large engineering organizations, so this balance must be achieved across many teams of people working on various components. This paper uses optimization theory to derive a m...

Optimal design and mathematical model applied to establish bioassay programs.

Bioassays can be used to estimate the initial intake I for the case of an acute intake exposure for an individual worker. To evaluate the effective dose, apart from I, we need to know other parameters such as activity median aerodynamic diameter (AMAD) or the fraction absorption ( f(1)) in the blood from the GI tract, but in an accident situation these parameters are often unknown. The bioassay...
