Abstract:

The Cal Poly CubeSat Laboratory (CPCL) is currently facing unprecedented engineering challenges—both technically and programmatically—due to the increasing cost and complexity of CubeSat flight missions. In responding to recent RFPs, the CPCL has been forced to find commercially available solutions to entire mission critical spacecraft subsystems such as propulsion and attitude determination & control, because currently no in-house options exist for consideration. The commercially available solutions for these subsystems are often extremely expensive and sometimes provide excessively good perf

Abstract:

Recent interest surrounding large scale satellite constellations has increased analysis efforts to create the most efficient designs. Multiple studies have successfully optimized constellation patterns using equations of motion propagation methods and genetic algorithms to arrive at optimal solutions. However, these approaches are computationally expensive for large scale constellations, making them impractical for quick iterative design analysis. Therefore, a minimalist algorithm and efficient computational method could be used to improve solution times. This thesis will provide a tool for si

Abstract:

Unmanned Underwater Vehicles (UUV) in open-seas are highly nonlinear with system motions. Because of the complex interaction of the body with environment it is difficult to control them efficiently. Linearization is applied to system in order to design controllers developed for linear systems. To overcome the effects of disturbances, a mathematical model which will compensate all disturbances and effects of linearization is required. In this study first a mathematical model is formed wherein the linear and nonlinear hydrodynamic coeffi- cients are calculated with strip theory. After the basic

We present a new trajectory generation algorithm for autonomous guidance and control of unmanned vehicles from a given starting point to a given target location. We build and update incomplete a priori maps of the operating environment in real time using onboard sensors and compute level sets on the map reflecting the minimal cost of traversal from the current vehicle location to the goal. We convert the trajectory generation problem into a finite-time-horizon optimal control problem using the computed level sets as terminal costs in a receding horizon framework and transform it into a simpler

Abstract:

This paper addresses the problem of iterative optimization of the Kullback-Leibler (KL) divergence on discrete (finite) probability spaces. Traditionally, the problem is formulated in the constrained optimization framework and is tackled by gradient like methods. Here, it is shown that performing the KL optimization in a Riemannian space equipped with the Fisher metric provides three major advantages over the standard methods: 1. The Fisher metric turns the original constrained optimization into an unconstrained optimization problem; 2. The optimization using a Fisher metric behaves asymptotic

From the robust stabilization point of view, we propose two of robust control techniques and use them on the design of missile guidance law. When the missile pursuits the target, the acceleration of target is usually unknown and can be regarded as external disturbance. According to the robustness of sliding-mode control, we use Variable Structure Control scheme to design missile guidance law. Moreover, H-infinity control scheme is also proposed for missile interception. We wish the ratio of

Abstract:

In this Thesis a new Optimal control-based algorithm is presented, FLOP is part of a new class of algorithms the group of Mechatronic and Vehicle Dynamic Lab of Sapienza is developing under the name of Variational Feedback Controllers (VFC). The proposed method starts from classical optimal variational principles, usually part of the Pontryagin’s or Bellman’s methods, but it provides the user with the possibility to implement a feedback control, even in the presence of nonlinearities. In fact, even though Pontryagin approach provide the best solution for the considered system, it has an engine

碩士<br>國立交通大學<br>電控工程研究所<br>103<br>In this thesis, we have developed a guidance control laws for electric vehicles. Since the electric vehicle is a driverless car for this study, the control of vehicle is determined through the master control node of automotive network. The roadside nodes are placed sequentially in pairs on both sides of the road, so the road is a path with detection capabilities. Therefore, each two roadside node divides the road into many segments. The roadside nodes build a coordinate system of the path before the vehicle enters. The master control node analyzes the current

Abstract:

The development of a self-contained, onboard, fully autonomous trajectory guidance tool for spacecraft is presented. To be considered completely autonomous requires the capability to both identify an appropriate startup solution, and then use that solution to target a set of user-defined path and endpoint constraints. To minimize the cost of flight software development and validation, both the generation of the startup solution and the targeting algorithm are designed to be as computationally efficient as possible. This study addresses both the determination of a startup arc and the subsequent

Abstract:

碩士<br>元智大學<br>機械工程學系<br>94<br>The path tracking of autonomous flying is an important performance index for UAV (unmanned air vehicle). In this paper, we have developed some virtual fuzzy logic controllers to simulate various 2D flying combinations of linear courses successfully by means of Matlab codes and its toolbox ODE45 step by step. These combinations include any straight courses, any rectangle-like four linear courses and combinations of arbitrary straight flying paths. Furthermore we utilize real coded GA (Genetic Algorithm) to tune the ranges of membership functions, and then promote

Abstract:

A guidance, navigation, and control (GN&C) module is being designed and fabricated as part of a series of CubeSats being built by the Satellite Design Laboratory at the University of Texas. A spacecraft attitude control simulation environment called StarBox was created in order to perform trade studies and conduct performance analysis for the GN&C module. Navigation and control algorithms were tested using StarBox and then implemented onto an embedded flight computer. These algorithms were then tested in a hardware-in-the-loop simulation. In addition, the feasibility of utilizing advanced cons
