Adaptive Autopilot Design for BTT Missile Based on Parameter Space Method

For the falling system performance caused by parameter-uncertainty in project,this paper designed a model reference adaptive autopilot for a certain BTT missile based on the parameter space method.At first,the gain of inner-loop controller is obtained by the parameter space method which can keep the robustness of system.Then,the model reference adaptive controller is designed for acceleration-loop to improve the response of local nonlinearity property.At the same time,this method can also increase the rapidity of system for adjusting disturbance.Finally,the digital simulations are presented to verify the validity of this method.
