Augmented State Linear Covariance Applications For Nonlinear Missile Engagements, Jeffrey Scott Clawson
Augmented State Linear Covariance Applications For Nonlinear Missile Engagements, Jeffrey Scott Clawson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Sustained actuator saturation is a common occurrence for missile engagements. The saturation nonlinearity creates some difficulty for high-fidelity linear analysis methods. This dissertation investigates three methods of modeling actuator saturation in an advanced linear analysis. The linear covariance tools from this dissertation run extremely fast and provide several advantages over other linear missile engagement analysis methods. First, a simulation is developed and validated for a target engagement scenario without actuator saturation. Next, saturations are introduced to the problem, along with the first analysis method: statistical linear covariance analysis. This method combines the augmented state linear covariance framework with the statistical …
