Abstract :
For missiles with blended aerodynamic surface and reaction jet control, uncertain model and cross-coupling propose two challenges to autopilot design. A kind of nonlinear controller combining dynamic inversion and fuzzy cerebellar model articulation controller (FCMAC) network was designed for the missile. The nonlinear control law of the agile missile was constructed by dynamic inversion. Then, FCMAC network was used to compensate the influence of system uncertainties. This method avoids the timescale separation that is impossible to agile missile. To enable missile to track desired signals in wide area field, the adaptive weight update rules were derived from Lyapunov theorem. Finally, numerical simulations under different conditions were carried out. The results show the fast-response and robust performance of the proposed controller
