摘要
提出了一种基于模型的逆控制技术与基于规则的模糊控制技术相结合的直升机飞控系统设计方法,以解决当直升机数学模型不确定时飞控系统的设计问题,并设计了相应的逆控制器及模糊控制器。仿真结果表明,所设计的飞控系统具有良好的动态响应、较强的鲁棒性及满意的解耦效果,在直升机飞行控制系统的设计中有一定应用价值。
This paper puts forward an idea which combines model-based inversion control technique with rule-based fuzzy logic control technique to deal with the problem of designing a control system for an object which has uncertain or inaccurate mathematical dynamic model. Then, it gives out the method to design inversion controller and fuzzy logic controller. Simulation results show that the flight control system based on inversion control technique and fuzzy logic control has good performance,better robustness and effect of decoupling. It has potential application ability in the design of flight control system for helicopters.
