| 摘 要： | 新型精确制导导弹为了获得更大的机动性、敏捷性和更高的命中精度,大多采用了推力矢量控制或反作用推力控制.讨论了敏捷性导弹的动力学特性及数学建模,并针对一类反作用推力控制的导弹提出了一种具有实时逻辑切换能力的变结构模型跟踪控制方案,为减弱一般变结构控制系统的抖颤问题,在变结构控制系统中引入简单的模糊规则,有效抑制了变结构系统的抖颤,同时进一步增强了控制系统的鲁棒性.数学仿真表明控制方案的有效性.

| Abstract: | Advanced agile missiles possess maneuverability, agility and accurate guidance performance by adopting thruster vector control or reaction control system thruster. System dynamics and modelling of the advanced agile missiles is investigated, a variable structure model following control approach for the agile missile with reaction control system thruster is presented, real time logic switching control law is used. In order to overcome the chattering problem existing in most variable structure control systems, simple fuzzy control laws are introduced in the variable structure control system, which proved to be effective in not only chattering problem subduction bust also the system robustness enhanced. Numerical simulation results are given to illustrate the effectiveness. |
