摘　　要：提出BTT飞行器的一种鲁棒解耦控制方法。针对飞行器具有非线性、强耦合、多输入多输出(MIMO)等特点,从飞行器数学模型分析通道间耦合产生的原因,并采用Gershgorin圆的方式,定量的分析系统的对角优势度;然后利用粒子群优化算法(PSO)得到小偏差线性模型的鲁棒解耦矩阵,使得系统满足对角优势的性质;最后设计鲁棒控制器,经仿真结果验证表明,该解耦方式的控制效果良好,并具有较强的工程应用价值。A robust decoupling control method for BTT vehicle is proposed. According to the vehicle＇s characteristics such as nonlinearity, strong coupling and MIMO, firstly, the result of the coupling between channels is analyzed on the construct of BTT vehicle＇s mathematical model. And then, Gershgorin Circle is adopted to quantificationally analyze the diagonal dominance of this system. Next, using PSO, a robust decoupling matrix of the small- signal linearized models is deduced, which makes the system fulfill the diagonal dominance. Finally, simulation results show that robust decoupling controller is effective and easy for engineering application.
