导弹复合控制系统的模糊逻辑控制分配

针对空空导弹复合控制系统中的控制分配问题,提出了一种模糊逻辑控制分配算法。采用动态面控制方法设计了复合控制量的控制律。在设计过程中,利用扩张状态观测器估计汇总不确定项,并采用光滑二阶滑模控制算法设计了控制律,达到了提高鲁棒性和削弱抖振现象的目的。应用模糊逻辑控制分配算法将复合控制量分解为直接力控制指令和舵偏角控制指令。为了检验所设计的复合控制系统的控制效果,对采用基于模糊逻辑控制分配算法的复合控制系统和传统的气动力控制系统进行了对比仿真实验。仿真结果表明,所设计的复合控制系统具有更好的控制效果。

Fuzzy Logic Control Allocation of Missile Compound Control System

A fuzzy logic control allocation algorithm is proposed to deal with the control allocation problem in compoundcontrol system of air-to-air missile. The control law of compound control variable is designed by dynamic surface controlmethod. In design process, the extended state observer is used to estimate the lumped uncertainties, the smooth second-or?der sliding mode control algorithm is adopted to design the control law, the purpose of improving robustness and weaken?ing the chattering phenomenon is achieved. The fuzzy logic control allocation algorithm is used to decompose the com?pound control variable into lateral thrust control command and rudder deflection angle control command. In order to testthe control effect of designed compound control system, the comparative simulation experiments are performed for both thecompound control system based on fuzzy logic control allocation algorithm and the traditional aerodynamic force controlsystem. The comparison of simulation results shows that the designed compound control system has better control effect.
