摘　　要：研究了模型逆控制方法应用于IFPC一体化控制器的设计问题。简要介绍了模型逆非线性控制方法的概念、特点。在此基础上,将模型逆与经典控制相结合,设计了IFPC控制律,并进行了时域仿真与飞行品质分析。结果表明,所设计的控制律无需增益调参即可实现各状态的指令跟踪,并具有较强的鲁棒性能;系统具有典型的一阶/二阶动态特性,满足一级飞行品质要求。This paper deals with the application of model inversion control method in IFPC systems. The concepts and characteristics of model inversion control method are introduced. On the basis of this, the IFPC control law through combination of model inversion and classical control is designed. Then, the time-domain simulation and flying quality analysis are given. The results show that the designed control law （FCL） can meet the tracking precision requirement without gain scheduling, and has a strong robustness to parametric disturbances; the IFPC system has first/second-order dynamic characteristics, which meets the requirements for the 1st level flying quality.
