Get this from a library. An adaptive numeric predictor-corrector guidance algorithm for atmospheric entry vehicles. [Kenneth Milton Spratlin; United States. National Aeronautics and Space Administration.].
A numerical predictor-corrector method was investigated in  for adaptive and accurate entry guidance of low-lifting entry vehicles, and the performance of the algorithm was improved and. An adaptive predictor–corrector reentry guidance algorithm with self-defined way-points is proposed.
In the guidance process, the reentry trajectory is divided into the predictor–corrector. Upcoming landing missions to Mars will require on-board guidance and control systems in order to meet the scientific requirement of landing safely within hundreds of meters to the target of interest.
More specifically, in the longitudinal plane, the first objective of the entry guidance and control system is to bring the vehicle to its specified velocity at the specified altitude (as required Cited by: The dramatic increase in computational power since the Apollo program has enabled the development of numerical predictor-corrector (NPC) entry guidance algorithms that allow on-board accurate determination of a vehicle’s trajectory.
These algorithms are sufficiently mature to be flown. They are highly adaptive, especially in the face of extreme dispersion and off-nominal situations Cited by: The all-coefficient adaptive predictor–corrector guidance method is proposed in section 3, which concludes the stability analysis, the process constraints control and the whole guidance scheme.
Numerical simulations on a RLV are presented to demonstrate the application of Cited by: 8. An adaptive numeric predictor-corrector guidance is developed for atmospheric entry vehicles which utilize lift to achieve maximum footprint capability.
Applicability of the guidance design to vehicles with a wide range of performance capabilities is desired so as to reduce the need for algorithm redesign with each new vehicle. Motivated by these considerations, we present in this work a methodology for model-based control of nonlinear hybrid process systems using an adaptive predictor corrector strategy.
The approach aims to stabilize the process with minimal sensor-controller information transfer. The liquid level is initially maintained at 25 cm. Two step changes, each of magnitude 5 cm is introduced in the set-point at 10 th and 40 th minute and the change in process variable is shown in Fig.
The evolution of corresponding controller outputs is shown in Fig. The performance indices IAE and TV are shown in Table IAE of NMBC is minimum, whereas the IAE of the proposed Author: S.
Kapil Arasu, J. Prakash. Journal of Atmospheric and Oceanic Technology() Sparsity-Aware Precorrected Tensor Train Algorithm for Fast Solution of 2-D Scattering Problems and Current Flow Modeling on Unstructured by: In this paper an Improved Predictor Corrector (IPC) method to solve the “fuzzy initial value problem” is proposed.
The IPC method is obtained by combining an explicit three‐step method and an implicit two‐step method. These methods are compared with existed the methods, where the proposed methods proved to have more by: 2. Atmospheric entry has been performed by numerous vehicle systems since the dawn of the space age.
Early robotic systems, such as that used by the Corona program, utilized an entry vehicle to return lm containing orbital reconnaissance imagery to the surface of Earth . Atmospheric entry has also been a major part of every human space.
