Parameter Identification of Spin-Stabilized Projectiles Using a Modified Newton-Raphson Minimization Technique.

Modified Newton - Raphson methods for optimal control of quantum systems

A Modified Newton Method for Minimization I

Some promising ideas for minimizing a nonlinear function, whose first and second derivatives are given, by a modified Newton method, were introduced by Fiacco and McCormick (Ref. 1). Unfortunately, in developing a method around these ideas, Fiacco and McCormick used a potentially unstable, or even impossible, matrix factorization. Using some recently developed techniques for factorizing an inde...

Heat and Mass Balance Using Constraint Equations, a Spreadsheet, and the Newton-raphson Technique

To work out a balance problem in a factory, two simple rules are applied. Firstly, a steady state condition applies. This gives rise to the second rule: what goes in must come out. Based on these rules, the equations for heat and mass balances can be derived. There are several packages available to solve these rules or constraints. The choices include Simulink and Sugars. The use of these packa...

A Decimal Floating-Point Divider Using Newton-Raphson Iteration

Since its founding in 1925 as the patenting and licensing organization for the University of WisconsinMadison, WARF has been working with business and industry to transform university research into products that benefit society. WARF intellectual property managers and licensing staff members are leaders in the field of university-based technology transfer. They are familiar with the intricacies...

Adaptive Control of a Spin-Stabilized Spacecraft Using two Reaction Wheels and a 1DoF Gimbaled-Thruster

In impulsive orbital maneuvers, a large disturbance torque is generated by the thrust vector misalignment from the center of mass (C.M). The purpose of this paper is to reject the mentioned disturbance and stabilize the spacecraft attitude, based on the combination of a one degree of freedom (1DoF) gimbaled-thruster, two reaction wheels (RWs) and spin-stabilization. In this paper, the disturban...
