Control Systems for High Frequency and Hybrid Flight Motion Simulation

Control system methods, architectures and algorithms will be developed to extend the meaningful bandwidth for flight motion simulators (FMS). This will prove valuable for testing missile seekers including image motion compensation algorithms. After anassessment of requirements, two main efforts will be conducted. One will concentrate on extending current HWIL test capabilities by both feedback and feedforward control for standalone high frequency FMS. Current algorithms will be reviewed, andapproaches for advancing, adapting and combining algorithms will be studied. Adaptive inverse control will be evaluated. For each algorithm, most of the development will use software simulation, but existing high frequency simulators will be used ifavailable. The second major thrust will be in the integration of high frequency and low frequency conventional FMS in a hybrid architecture. Dynamic interaction and control system structure will be considered, with a goal of meeting HWIL simulationrequirements of interest in the missile test community. In Phase 2, the research will focus on further development of standalone high frequency FMS or integrated hybrid systems, again based on requirements of current and future missile developmentprograms. The new control systems will be demonstrated with construction of a new HWIL system or enhancement of existing systems. The primary application of this technology will be in testing missile seekers, including those associated with the THAADprogram. Customers will include organizations with existing conventional FMS systems and those desiring to test performance affected by high frequency jitter. The control algorithms developed will also support motion control systems for industrialcontrol and manufacturing.
