Item Control with Disturbance Preview and Online Optimization(Institute of Electrical and Electronic Engineers, 2004-02) Jarvis-Wloszek, Zachary; Philbrick, Douglas; Kaya, M. Alpay; Packard, Andrew; Balas, Gary J.We present an intuitive and self-contained formulation of a stability preserving receding horizon control strategy for a system where limited preview information is available for the disturbances. The simplicity of the derivation is due to (and its benefits somewhat offset by) a set of stringent and highly structured assumptions. The formulation uses a suboptimal value function for terminal cost, and relies on optimization strategies that only require a trivial improvement property, allowing implementation as an “anytime” algorithm. The nature of this strategy’s performance is clarified with linear examples.Item Longitudinal Motion Control of a High-Speed Supercavitation Vehicle(Sage Publishing, 2006-06-15) Arndt, Roger E.A.; Balas, Gary J.; Bokor, Jozsef; Vanek, BalintThis article focuses on theoretical developments in modeling and control of High-Speed Supercavitating Vehicles (HSSV). A simplified model of longitudinal dynamics is developed for control, and a dynamic inversion based inner-loop control technique is proposed to handle the switched, time-delay dependent behavior of the vehicle. Two outer-loop control schemes are compared for guidance level tracking. Various aspects of disturbance characteristics and actuator dynamics are investigated and analyzed.
