Adaptive Sliding Mode Guidance Law with Prescribed Performance and Terminal Angle Constraint [PDF]

Hangkong bingqi
To address the interception of maneuvering targets in three-dimensional space with terminal impact angle constraints and the issue of initial control input saturation, this paper proposes a prescribed performance-based adaptive sliding mode guidance law ...

Truncated and Helix-Constrained Peptides with High Affinity and Specificity for the cFos Coiled-Coil of AP-1 [PDF]

, 2013
Protein-based therapeutics feature large interacting surfaces. Protein folding endows structural stability to localised surface epitopes, imparting high affinity and target specificity upon interactions with binding partners.

Terminal Angle Constraint Guidance Law Based on SDRE Method

IOP Conference Series: Earth and Environmental Science, 2019
In this paper, a new guidance law based on SDRE method is designed to solve the problem of terminal angle constraint of a missile by using nonlinear kinematics model and dynamic model of a missile. The constraint of collision angle can be realized by the guidance law under the condition of satisfying the requirement of miss distance of terminal ...

Two-Phase Optimal Guidance Law considering Impact Angle Constraint with Bearings-Only Measurements

International Journal of Aerospace Engineering, 2017
The implementation of advanced guidance laws with bearings-only measurements requires estimation of the range information. To improve estimation accuracy and satisfy the impact angle constraint, this paper proposes a two-phase optimal guidance law ...

Optimal Look-Angle Guidance with Field-of-View and Impact Angle Constraints for Strapdown Munition

International Journal of Aerospace Engineering, 2022
A strapdown seeker with limited field-of-view (FOV) can simplify and decrease cost of the guidance system for a munition. However, the inherent defect of the strapdown seeker is that it could not provide the necessary line-of-sight (LOS) angular ...

Minimum time control of the rocket attitude reorientation associated with orbit dynamics [PDF]

, 2015
In this paper, we investigate the minimal time problem for the guidance of a rocket, whose motion is described by its attitude kinematics and dynamics but also by its orbit dynamics.

Second-Order Sliding Mode Guidance Law considering Second-Order Dynamics of Autopilot

Journal of Control Science and Engineering, 2019
Aiming at the requirement that some missiles need to meet certain impact angles when attacking targets, we consider the second-order dynamic characteristics of autopilot, thereby proposing a second-order sliding mode guidance law with impact angle ...

Spatial Constraint Corrections to the Elasticity of dsDNA Measured with Magnetic Tweezers [PDF]

, 2007
In this paper, we have studied, within a discrete WLC model, the spatial constraints in magnetic tweezers used in single molecule experiments. Two elements are involved: first, the fixed plastic slab on which is stuck the initial strand, second, the ...
