Abstract:
The Pyramidal Reaction Wheel Platform, or PRWP, is used to simulate three-axis controls in a torque free space-like environment. The primary purpose of the system will be to evaluate the effects of conjoining sensors to maximize pointing accuracy. Furthermore, the system will incorporate a star tracker in conjunction with a Simulated Star Field (SSF) to better estimate the PRWP orientation. For the sake of this document, however, the goal is to implement a gyroscope, wheel rate sensors, and a make-shift accelerometer—to the PRWP—and integrate a controls algorithm such that three-axis controls

Abstract:
The transmissions of present heavy wheel loaders are in general based on torque converters. The characteristics of this component suits these machines, especially in that it enables thrust from zero vehicle speed without risk of stalling the engine, without active control. Unfortunately, the component also causes losses which might become large compared to the transmitted power. One approach for mitigating these losses is to switch to a continuously variable transmission. Changing to such a system greatly increases the possibility, and the need, for actively selecting the engine speed, and her

Attitude control laws that use control moment gyros (CMGs) and momentum wheels are derived with nonlinear techniques. The control laws command the CMGs to provide rapid angular acceleration and the momentum wheels to reject tracking and initial condition errors. Numerical simulations of derived control laws are compared. A trend analysis is performed to examine the benefits of the derived controllers.

Heavy haul railway operations permit the transport of huge volumes at lower cost than other modes of transport. The low cost can only be sustained if the maintenance costs associated with such railway operations are minimised. The maintenance costs are mainly driven by wheel and rail damage in the form of wear and rolling contact fatigue (RCF). Low wear rates in the wheel-rail interface have resulted in an increase in the prevalence of rail RCF, thereby increasing rail maintenance costs.

碩士<br>國立成功大學<br>工程科學系碩博士班<br>92<br>The inertia wheel pendulum system is an unstable nonlinear system. The mechanism of this system is not complicated. Because of this, this system provides a platform for verifying the effectiveness of different control schemes. In this thesis, it is first shown how to build up an inertia wheel pendulum system. This system includes an armature controlled DC motor, a wheel, a pendulum, and an optical rotary encoder. Then the mathematical model of the inertia wheel pendulum system is derived and also the DC motor model is built. The system identification method i

Many researchs about vehicle behavior focus on the new steering concept and many reports prove that the system of 4WS is not only better in stability but also has better steer- ing performance than the traditional front wheel steering (FWS) vehicle. This research will use the 4WS system in the vehicle model with four wheel independent suspension and also consider that the mass cent

Abstract:
The Reaction Wheel Pendulum (RWP) is an interesting nonlinear system. A prototypical control problem for the RWP is to stabilize it around the upright position starting from the bottom, which is generally divided into at least 2 phases: (1) Swing-up phase: where the pendulum is swung up and moves toward the upright position. (2) Stabilization phase: here, the pendulum is controlled to be balanced around the upright position. Previous studies mainly focused on an energy method in swing-up phase and a linearization method in stabilization phase. However, several limitations exist. The energy m

In order to have broader extension of the theories, nonlinear model is necessary. In this thesis a lot of attentions are paid to the construction and analysis of the model and the thesis are divided into four parts. First part is the construction of vehicle model, and both linear and nonlinear model will be introduced. Furthermore, we used front wheel steering angle feedforward to build up the nonlinear vehicle model. Second Part
