一种基于自适应模糊系统的导弹自动驾驶仪设计方法
Design Method for Autopilot of Missile Based on Adaptive Fuzzy System
摘要
Abstract
Aiming at uncertain nonlinear system of missile, a design approach based on dynamic inverse and adaptive fuzzy system theory was presented. Based on nonlinear model of missile, dynamic inversion controllers were designed in both fast loop and relatively slow loop in order to realize the nonlinear decoupling,and the uncertainties and disturbances of system were introduced to relatively slow loop. According to the tracking error,the adaptive fuzzy system was constructed to approximate the uncertain nonlinear systems, and the weight parameters of fuzzy system changed on-line. The adaptive fuzzy control laws under the conditions that upper hound of the least approximation errors was unknown,were designed in relatively slow loop so as to compensate the effects of the uncertainties and disturbances on the control system performance. The simulation result proves the effectiveness of the control method.关键词
