Braking and attitude control of lunar lander in active descent stage

Control and Simulation of an Autonomous Lunar Lander

The Autonomous Lunar Demonstrator (ALDER) project was developed at NASA Ames Research Center to demonstrate autonomous decision making on a Lunar lander spacecraft capable of performing autonomous hop maneuvers. Towards these objectives, a conceptual spacecraft design was created to accomplish the mission, a simulation environment was developed, and a control system was designed and implemented...

Design and Simulation of Lunar Soft Lander

In this paper, dynamic simulation and analysis for designing the soft landing of a lunar lander is focused. The primary objective of the lunar lander is to land safely on the surface of moon, without causing the lunar lander to topple and must attenuate the landing loads to preclude damage to the lander structure. The dynamic structural model of lunar lander is modelled and simulation described...

Time Optimal Closed - Loop Fuzzy - Control Strategy for Nonlinear Lunar Lander Mission

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
