Three dimensional adaptive dynamic surface guidance law accounting for autopilot lag

Abstract: A new adaptive guidance law accounting for the autopilot lag as a second-order dynamics is proposed utilizing dynamic surface control. The target acceleration is considered as a bounded uncertainty, but its upper bound cannot be estimated as a priori. Considering the unknown parameter uncertainty, an update law is designed via Lyapunov approach. The guidance acceleration command input is determined by a dynamic surface control law with a parameter update law. Some first-order low-pass filters are introduced in… Show more

“…In [21], by introducing smooth tangent function and Nussbaum function to deal with the problem of input saturation, an adaptive dynamic surface three-dimensional guidance law is designed. In [22,23], by introducing an adaptive algorithm to estimate the upper bound of target acceleration online, an adaptive threedimensional guidance law with acceleration constraint is designed by using adaptive algorithm and dynamic control method, but the state of the guidance system can only be guaranteed to be uniformly bounded. In order to further improve the interception probability for high maneuvering targets.…”

“…However, in practice, the missile autopilot dynamics can be well approximated as a second-order system. For example, based on dynamic surface control, some two-dimensional (Qu and Zhou, 2012; Zhou et al, 2013) and three-dimensional guidance laws (Xu and Zhou, 2014) were designed. However, the proposed guidance law in Qu and Zhou (2012), Zhou et al (2013), and Xu and Zhou (2014) cannot guarantee finite time convergence.…”

However, the proposed guidance law in Qu and Zhou (2012), Zhou et al (2013), and Xu and Zhou (2014) cannot guarantee finite time convergence. Thus, in He et al (2015b), a two-dimensional guidance law with impact angle constraints and finite time convergence using the sliding mode backstepping method was developed.…”

“…Actually, the autopilot 2 International Journal of Aerospace Engineering is of high-order dynamics. As an improvement, guidance laws in [4][5][6] are designed accounting for the autopilot as secondorder dynamics. In [7][8][9], finite-time convergence guidance laws in the presence of autopilot lag are studied, which guarantee that the line-of-sight angular rate converges to zero in finite time.…”
