Implementation method of Mosaic mode based on satellite attitude maneuver
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Mosaic is a hybrid mode of spotlight and ScanSAR, which can image a large coverage at a high resolution. In this paper, an implementation method of Mosaic mode based on satellite attitude maneuver is presented. By choosing proper satellite attitude, we can obtain the radar beam pointing direction and ground footprint orientation that are required by ...

Maneuver mode analysis and parametric modeling for hypersonic glide vehicles
Aerospace Science and Technology, 2021Abstract The maneuver modes in the glide phase are explored from the perspective of hypersonic vehicle defense in this study, and a novel maneuver mode description approach is proposed. The longitudinal and lateral maneuver modes' mechanisms and evolution laws are explored.

Sliding mode attitude control of a small satellite for ground tracking maneuvers
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000This paper deals with spacecraft attitude control using sliding mode techniques. Two distinctions of the proposed method from most reported methods are: 1) the measure of attitude error used is intrinsically defined, Euclidean-geometric, and intuitive; and 2) a novel, dynamically nonlinear sliding function is used that results in a simple control law ...

On spacecraft maneuvers control subject to propellant engine modes
ISA Transactions, 2015The paper attempts to address a new control approach to spacecraft maneuvers based upon the modes of propellant engine. A realization of control strategy is now presented in engine on mode (high thrusts as well as further low thrusts), which is related to small angle maneuvers and engine off mode (specified low thrusts), which is also related to large ...

An application of sliding mode control to vehicle steering in a split-mu maneuver
Proceedings of the 2003 American Control Conference, 2003., 2004In this paper a sliding mode integral action controller and sliding mode observer are used to enhance vehicle stability in a split-/spl mu/ maneuver. Anti-lock braking systems (ABS) have become an integral part of modern cars, and they have dramatically improved vehicle handling in braking manoeuvers.

Predictive Sliding Mode Control for Lane Changing under Overtaking Maneuver
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020A lane change assist control system autonomously steers an ego vehicle to an adjacent lane when there is another vehicle moving slower in front of it. It may cause disruptions and oscillations and consequently influence the capacity of the road by leaving voids and reducing flow.

Predictive control with sliding mode for autonomous driving vehicle lateral maneuvering
2017 American Control Conference (ACC), 2017An innovative paradigm of path planning and control is proposed for autonomous driving vehicles. The scheme applies predictive control with sliding mode to solve the problem of path planning in the vehicle coordinates and control. The path for lateral motion is given by a sliding hyperplane in terms of lateral error and velocity in the vehicle ...

Impact of Mode Decision Delay on Estimation Error for Maneuvering Target Interception
IEEE Transactions on Aerospace and Electronic Systems, 2011For highly maneuvering target interception in terminal guidance, state estimation error is characterized. First, the estimator's state space model is constructed with a stochastic linear hybrid system (SLHS) in the presence of the unknown lateral acceleration of the evader.

Optimal Sliding-Mode Guidance Law for Fixed-Interval Propulsive Maneuvers
2006 IEEE International Conference on Control Applications, 2006An optimal strategy based on minimum control effort with terminal position constraint is developed for an exoatmospheric interceptor with a fixed-interval guidance time. It is then integrated with sliding-mode control theory to drive an optimal sliding-mode guidance law for fixed-interval guidance time. In addition, this guidance law is generalized for
