小型巡飞弹气动阻力系数自适应估计方法
Adaptive Estimation for Drag Coefficients of Small Loitering Missile
摘要
Abstract
To improve the convergence speed and stability of aerodynamic drag coefficients estimation of small loitering missile,an adaptive aerodynamic-parameter estimation approach which can guarantee the prescribed performance was proposed. The linear parametric velocity equation was obtained by establishing the dynamic model of loitering missile. Aiming at the problem that the transient performance of the error convergence process can not be directly designed in the previous parameter estimation method,the prescribed performance function was introduced into the adaptive parameter estimation,and the error transformation of the estimated error of aerodynamic drag coefficients was carried out,and the a-daptive aerodynamic parameter estimation method was developed. The simulation results show that the proposed approach can achieve the convergence of parameter estimation in a short time and ensure the transient performance and steady-state performance of the aerodynamic parameters compared with the tra-ditional adaptive parameter estimation. The simulation results prove the good effectiveness of the proposed method.关键词
