| 摘 要： | 根据机动中机翼摇晃的主要动态特性,建立了多维非线性模型;在动态逆控制律的设计中,特别针对外环中状态变量多于操纵舵的问题,构造了基于加权最小二乘逆的控制结构,并引人积分反馈以弥补最小二乘近似逆及模型不确定性等因素导致的系统逆误差.仿真实验结果表明,所设计的加权最小二乘逆控制器,不仅能确保战机准确地跟踪机动指令,更能有效地...

| Abstract: | In this paper,a seven-dimension wing rock model in maneuver was developed through reasonable simplifications of aircraft general model as well as a considerate access to wing rock's primary properties.Afterwards,a special weighted least-square dynamic inversion controller was then structured to deal with the issue regarding the mismatch in number between controlled states and rudders in the outside loop,and some PI feedback law was brought in for inversion errors caused mainly by such approximate inversion ... |
