摘要

This paper presents a blending principle of tail fins and reaction jets to achieve a fast response for a dual-controlled missile under a slew-rate limit. The blending principle can be categorized as controlling either the net force or the net moment according to how the two actuators cooperate with each other. When compared with controlling the net moment, controlling the net force of aerodynamic lift and jet thrust allows direct control of the acceleration, thus enabling a much faster response but at the expense of large control effort. In this work, for the initial transient period a force controller is designed to achieve fast response under the slew-rate limit, then the transition control is proposed, which begins with force control and makes a transition to moment control to reduce the control usage. This transition does not involve switching from one controller to the other. Rather, the angle of attack is properly shaped corresponding to the desired moment, allowing a smooth and stable transition from force control to moment control. The smooth transition by the proposed strategy from force control to moment control is demonstrated with nonlinear missile dynamics. The proposed approach shows a very fast response, while its input usage is almost same as the conventional moment control.
