A hardware control system framework is presented for both real-time and batch six-degree-of-freedom simulation. This framework allows stabilization and control with multiple command options, from body rate control to waypoint guidance. Also, Autopilot commands can be used to operate the simulation in a hardware in-the-loop environment. This control system framework is created by using direct missile state feedback with nonlinear dynamic inversion. A direct control allocation scheme is used to command missile effectors. Online B -matrix estimation is used in the control allocation algorithm for maximum algorithm flexibility. Primary uses for this framework include conceptual design and early preliminary design of missile, where missile models change rapidly and knowledge of missile six-degree-of-freedom performance is required. A simulated airbreathing hypersonic cruise missile and a simulated high performance air to air missile are controlled to demonstrate the flexibility and utility of the control system.
