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。
The model inverse control method is applied to the design of IFPC integrated controller. The concept and characteristics of the inverse nonlinear control method are briefly introduced. Based on this, IFPC control law is designed by combining model inverse with classical control, and time-domain simulation and flight quality analysis are carried out. The results show that the proposed control law can realize the instruction tracking of all states without gain tuning, and has strong robustness. The system has the typical first-order / second-order dynamic characteristics to meet the requirements of first-class flight quality.
