Abstract

A new compound control method for missile with canard and tail rudders is presented in this paper. Firstly, the mathematical model of missile with canard/tail rudder is built and linearized using the small disturbance method. Then, the canard/tail rudder compound control system is created; the canard/tail rudder compound allocation strategy is designed based on the sequential quadratic programming method. Finally, the compound control method is verified on Matlab/Simulink. The simulation results show that the compound control method can not only ensure the high dynamic and steady state performance of the control system, but also ensure the high maneuverability of the missile in whole airspace with low drag, thus proving the algorithm in this paper to be reliable and effective.

摘要

提出了一种具有鸭舵/尾舵多操纵面的导弹复合控制方法。首先建立了导弹的数学模型并进行了小扰动线性化，构建了鸭舵/尾舵复合控制系统，基于序列二次规划法设计了鸭舵/尾舵复合分配策略，并在Matlab/Simulink平台上进行了仿真验证。仿真结果表明，设计的鸭舵/尾舵复合控制系统不仅具有良好的动态性能和稳态性能，还能够在减小阻力的同时确保导弹从低空低速到高空高速都具备高机动能力，证明了新算法具有较高的可信性和实用性。
