面对称导弹离散反演BTT控制器设计与仿真

Design and Simulation of Discrete Backstepping BTT Controller for Plane-Symmetrical Missile

以面对称导弹为控制对象,从工程实际应用角度研究了非线性离散反演倾斜转弯(BTT)控制器设计问题。采用模拟化设计方法,将连续反演BTT控制器离散后获得离散控制器。通过混合仿真较全面地验证了离散控制器的稳定性和动态性能:离散控制器虽然比连续控制器的性能有所降低,但离散控制器在鲁棒性、解耦特性等方面,仍然能够达到设计目标要求,这对于工程实际中常用的以计算机解算控制信号的方法来说具有重要实用价值。另外,所设计的离散反演BTT控制器对信号噪声的干扰也具有较强的适应性,具有良好的工程应用前景。

A nonlinear discrete backstepping bank-to-turn （BTT） controller has been designed for the plane symmetrical missile from the point of view of practical engineering. The continuous time design （CTD） method is used to complete the designing of the discrete backstepping BTT controller. More com- prehensive hybrid simulation verifies the stability and performance of the discrete controller. Although the discrete controller performance is lower than the continuous controller, the robustness and decoupling specifications are also satisfied in terms of the design objectives and requirements. This is important for practical engineering applications, which solves the control signal by computers. Additionally, the con- troller also has a strong adaptability to the interference of noises. The proposed discrete backstepping BTT controller basically meets the requirements of practical engineering applications, and possesses a good prospect of engineering application
