Design of Missile Autopilot with Aerodynamic Lift and Reaction Jets Based on Auto Disturbance Rejection Controller

Abstract

First a new autopilot design model is presented for the interceptor missile with the blended aerodynamic lift and reaction jet. The reaction jet can improve the response speed, but the structure of control system becomes more complex. Therefore how to design control strategy properly is an urgent problem. Second, considering the discrete property of the lateral pulse jet thrusters and the continuous property of the aerodynamic fins, a kind of ADRC (active disturbance rejection control) autopilot system was designed for the aerodynamic lift/reaction jet missile. Finally, through a testing in the simulation of MATLAB, it is shown that, due to the sufficient utilization of the reaction jet, there is a significant improvement in the fast response and robust performance of the proposed controller. It is applicable to design the autopilot of aerodynamic lift and reaction jet blended missile.

Prescribed performance-based adaptive sliding mode control for the autopilot design of missile with lateral jets

“…Thus, the missiles that exploit aerodynamic fins at the tail and RCS near the front are much more agile than the conventional missiles, in particular, at low Mach or high altitude. 1 Moreover, the tail-control flight vehicle has a property of non-minimum phase behavior when tracking normal load command, 2 which causes the response lag, whereas the RCS can generate normal load without lag.…”
