Design of a TF Controller for Aerodynamic Missile Using Dynamic Inversion Sliding Mode Theory

According to singular perturbations theory, this paper adopted aerodynamic missile layered control algorithm, and divided terrain following controller into three layers, that is, velocity layer, attitude angles layer and angular velocities one. A dynamic inversion sliding mode control algorithm was proposed for the design of aerodynamic missile terrain following controller, at the same time the uncertain errors of missile system were adequately considered to guarantee the tracking errors converge exponentially. Finally nonlinear six-degree-of freedom simulations of one aerodynamic missile were done, from the results it can be seen that the missile can follow the terrain configuration accurately, and the simulation results also showed that the designed system had strong robustness and rapidly tracking capability.
