摘要

Anonlinear autopilot for a 155mmdual-spin guided projectile wasdesigned to deal with its highly nonlinear and strongly coupled lateraldynamics. The lateral autopilot design relies on NDI-based controland a TSS approach, distinguishing between inner (fast) and outer(slow) dynamics. Both loops were successfully linearized anddecoupled, and a simple linear controller was added to imposedesired settling time and overshoot requirements. Trajectory simulationswere done using a ZEM-based guidance law for nominal anduncertain cases demonstrating promising results. Future work willaddress a more detailed robustness analysis of the NDI-based controlleras well as antiwindup loops to ensure system stability in thecase of actuator saturations.
