Résumé :

This thesis presents an analysis framework to verify the stablility property of a closed-loop control system with a software controller implementation. The usual approach to verifying stability for software uses experiments which are costly and can be dangerous. More recently, mathematical models of software have been proposed which can be used to reason about the correctness of controllers. However, these mathematical models ignore computational details that may be important in verification. We propose a method to determine the instability of a closed-loop system with a software controller im

Laser tracking systems are an important aspect of the NASA space program, in particular for conducting research in relation to satellites and space port launch vehicles. Often, launches are conducted at remote sites which require all of the test equipment, including the laser tracking systems, to be portable. Portable systems are more susceptible to environmental disturbances which affect the overall tracking resolution, and consequently, the resolution of any other experimental data being collected at any given time.

碩士<br>國立成功大學<br>電機工程學系<br>102<br>This work presents the architecture and design of a three-phase digital pulse width modulation (PWM) controller chip for 400-W cascoded dc-dc converter operating at continuous conduction mode in hybrid fuel cell system. A scheme for sensing three-output voltage and two-output current with an external 8-bit resolution analog-to-digital converter (ADC) is designed. To achieve the sensed values precisely, the data conversion to actual voltage and current from output of ADC is implemented which exploit the 20-bit fixed-point notation method. In addition, the suitab

The isolated method through second phase of DSP TMS320F28027 drives the first phase of high voltage device by PWM signal. In the same time, the varying-frequency method can be more efficacy than the current power design. The same-phase PWM is used to drive the second phase of synchronous rectification in order to replace the traditional rectified diode. In this thesis, the con

碩士<br>國立雲林科技大學<br>電機工程系碩士班<br>91<br>The design of a digital grid-connected inverter and a fast phase-locked-loop controller is presented in this thesis. Current-controlled inverters convert dc power generated by photovoltaic cells into ac power. The output of the inverter is directly connected to utility grid system to supply peak load. The parallel control of inverters is applied to increase the capacity and reliability of the system. Each module has an equal current distribution in steady-state operation. And in transient-state operation, the system demonstrates good performance for the step

Résumé :

碩士<br>國立交通大學<br>電機工程學系<br>102<br>This thesis presents the design and implementation of an FPGA-based digital current controller, providing a fully integrated solution for high-performance three-phase inverters. The synchronous coordinate current control algorithm is realized with dead-time compensation and one-shunt current sampling by using the introduced controller. First of all, DPWMMIN strategy is employed in the controller under considerations of linear range modulation and switching losses, based on the evaluation of three typical PWM methods, SPWM, SVPWM and DPWMMIN. In the DPWMMIN sche
