29. MultiBoom Computer Tool Formulation of the Equations of Motion for Different Smart Weapon Configurations is Cumbersome and Prone to Error
MultiBoom Models Each Element as Its Own Rigid Body with 6DOF
Constraint Forces and Moments are Treated at CONTROLS that are Selected to Satisfy the Constraint Equations
A Feedback Linearization Constraint Stabilization Controller is Created that Always Satisfies the Constraints
For a 3 Link System, 36 States Are Needed and 10 Constraint Controls are Used
In One Code/Algorithm MultiBoom Simulates Flight Mechanics of Multicomponent Smart Weapon Configurations
Dual Spin Projectiles, Gimbal Nose Projectiles, Tri Spin Projectiles, Moving Internal Mass Projectiles
30. MultiBoom Computer Tool For Each Rigid Body, the Standard 6 Degree of Freedom Rigid Body Equations Can Be Written As
31. MultiBoom Glue Code The Equations of Motion for All Bodies Can be Stacked Together into an Affine in Control Form
32. MultiBoom Glue Code We Directly Control the System Along the Constraint Manifold
