Agile missile autopilot design via time-varying eigenvalue assignment

This paper is concerned with control allocation strategies with two-time scale dynamic inversion which generate nominal control input trajectories. In addition, a robust flight control design method is proposed by using a time-varying control technique which is time-varying version of the pole placement of linear time-invariant system for an agile missile with aerodynamic fin, thrust vectoring control, and side-jet thruster. The control allocation algorithms proposed in this paper are capable of extracting the maximum performance by combining each control effector. The time-varying control technique for the autopilot design enhances the robustness of the tracking performance for the wide angle of attack range. The main results are validated through the nonlinear simulations with aerodynamic data.
