Adaptive Huber-Based Filter for Hypersonic Cruise Vehicle Navigation

Vehicle Trajectory Impacts of Adaptive Cruise Control

Adaptive Cruise Control (ACC) is assumed to have a potential to improve quality-of-service and safety and to reduce the environmental impact of the road traffic system. This paper use vehicle trajectories from traffic simulation to study impacts of ACC on vehicle acceleration and deceleration rates. The analysis is based on traffic simulations with car-following models including ACC functionali...

Vehicle Trajectory Effects of Adaptive Cruise Control

Adaptive Control of a Generic Hypersonic Vehicle

This paper presents an adaptive augmented, gain-scheduled baseline LQR-PI controller applied to the Road Runner six-degree-of-freedom generic hypersonic vehicle model. Uncertainty in control effectiveness, longitudinal center of gravity location, and aerodynamic coefficients are introduced in the model, as well as sensor bias and noise, and input time delays. The performance of the baseline con...

Formulation, Realization, and Demonstration of a Process to Generate Aerodynamic Metamodels for Hypersonic Cruise Vehicle Design

The desire to facilitate the conceptual and preliminary de­ sign of hypersonic cruise vehicles has created the need for simple, fast, versatile, and trusted aerodynamic anal­ ysis tools. Metamodels representing physics-based en­ gineering codes provide instantaneous access to cali­ brated tools. Nonlinear transformations extend the capa­ bility of metamodels to accurately represent a large de­ ...

Adaptive Pole Assignment Control for Generic Elastic Hypersonic Vehicle

This paper uses robust pole assignment method to design an adaptive velocity and altitude tracking control algorithm for the longitudinal model of a wave rider configuration air-breathing hypersonic vehicle, which has strong coupling between structure, propulsion and aerodynamics. Base on the elastic hypersonic vehicle model CSUAL_GHV, the simulations using adaptive robust pole assignment contr...
