基于二阶滑模控制理论的新型滚转稳定控制器

In order to counteract the undesired performance resulted from the rolling instability during the engagement phase, two novel methods for roll stabilization controllers based on the second-order sliding mode theory are proposed, which are based on the second-order sliding mode and the super-twisting algorithm, respectively. The first method can drive the roll angle converge to the desired value, while the second method not only can reduce the effect from the uncertainties in the aerodynamical parameters, but also can drive the roll rate converge to the desired value in finite time and stay in it. The chattering from the sliding mode algorithm can also be suppressed efficiently. The stabilization of the proposed controllers can be verified by constructing the Lyapunov function. The two proposed controllers and other reference controllers, which are respectively based on the linear sliding mode and the terminal sliding mode theories, are simulated contrastly and the effect from dynamic parameters in different attack angles is taken into account. The effectiveness, rapidity and robustness of the proposed controller is also verified by simulations.
