Abstract
A representation of robust nonlinear controller is proposed for ammunitions space trajectory control, which is combined adaptive dynamic inverse with sliding mode control. The control law design accomplishes 3-D trajectory tracking using attitude angle as control input, and includes the parameter update to correct force model errors, also sliding mode switch portion to resist winds. A transition reference trajectory which is easy to implement for tracking is designed, according to the actual location and speed of start control point. Simulation results show the proposed control strategy get accurate tracking performance of excellent dynamic characteristics in large uncertainties.
