舰载机着舰非线性反演控制方法研究进展

现在舰载机着舰控制以线性方法为主,而着舰的非线性特征和舰尾流等外部扰动可能导致线性方法失效,因此有待进一步研究非线性方法在着舰控制领域的应用。首先对非线性控制方法在舰载机着舰中的应用进行了综述,总结了各类非线性方法在着舰应用的优势及不足;然后针对反演这一非线性方法进行了重点概述:在分析舰载机传统反演方法不足的基础上,结合舰载机着舰过程中因为外界环境扰动和雷达噪声等因素可能引发的舵面受限,重点总结了受限指令反演方法在一般飞控的研究进展,研究了受限指令反演方法的优势和不足,探讨了将受限指令反演方法引入着舰控制的可能性;最后对未来发展方向进行了展望。

Research development in nonlinear backstepping control method of carrier-based aircraft landing

Currently the carrier-based aircraft landing control is mostly based on linear control methods, while the nonlinear characteristics of the model and the airwake disturbance may lead to the failure with these methods. Therefore, it is necessary to apply the nonlinear control method to the landing control field. Firstly, this paper reviews the nonlinear control method in application to carrier-based aircraft landing, and summarizes advantages and deficiencies of nonlinear methods. Secondly, the backstepping nonlinear method is emphatically analyzed. On the basis of traditional backstepping, and combining with the carrier-based aircraft landing rudder limited problem caused by the environmental disturbances and radar noise, the development of the constrained command filtered backstepping (CCFB) method is mainly summarized. The advantages and disadvantages of CCFB method are analyzed, and the possibility of introducing CCFB into the carrier-based landing control is discussed. Finally, the future development trends are forecasted.
