Integrated Simulation of Vehicular Systems with Stabilization,
Abstract
The feasibility of the use of overall simulation for the purpose of investigating response characteristics of systems which are influenced by interaction between the vehicle structure and the line of sight control subsystem is demonstrated. The effect of tube flexibility on pointing accuracy is demonstrated by inclusion of a flexible tube model. The model includes active control, but with the flexible element outside the control loop. A simplified model of the controlled system is used to identify proper actuation parameters required to maintain comparable control performance for different mass loads. The results are verified by simulation of the complete system. The model points out the relative importance of disturbance inputs resulting from vertical motion and pitch motion to line of sight control of systems with mass unbalance. It is shown that for certain classes of vehicles, mass balancing requires greater power input without significant improvement in pointing accuracy. (Author)
