摘要
将模糊控制理论应用于BTT导弹动态逆系统控制中,设计了BTT导弹控制系统鲁棒模糊控制器。首先应用动态逆系统方法设计BTT导弹控制器,然后用参数化线性模糊逻辑系统逼近动态逆控制器中的不确定项,并设计了自适应律以调整参数的变化,最后根据Lyapunov稳定性定理,证明了所提出的方法能保证BTT导弹控制系统是渐近稳定的,系统的跟踪误差将收敛到零。仿真结果表明,设计的控制器,对参数和外界扰动等不确定因素具有较强的鲁棒性和自适应性。
The robust fuzzy control theory was proposed in the BTT missiles dynamic inverse control system.The robust fuzzy controller of BTT missile control system was designed.The controller of BTT missiles was proposed by using dynamic inverse control method.Then parameterize linear fuzzy logic system was used to approximate the uncertainty item of dynamic inverse controller,with adaptive laws to be applied to attenuate the effects of approximate errors and external disturbances.Based on the Lyapunov stability theory,the global stability analysis shows that the states and tracking errors of the BTT missiles control system are uniformly bounded.The simulation results indicate that the designed controller has strong robustness and adaptability to the uncertainties of parameters and disturbances etc.
