【摘要】 本文重点研究了把ARM嵌入式处理器用于交流Buck-Boost电路中实现交流调压的数字控制问题,对Buck-Boost交流调压系统的构成、控制中采取的方式、控制策略和相关软、硬件进行了研究设计工作,并完成了原理性的验证。 首先对Buck-Boost电路应用于直流电路进行了分析,在此基础上,利用引入函数法对Buck-Boost电路应用于交流电路进行了理论分析,并推导出了输入和输出电压之间的数学关系,为实现数字控制奠定了基础。 在硬件方面,设计了一种新型Buck-Boost电路为主电路拓扑、以ARM嵌入式处理器为核心的检测显示及控制电路。算法方面,采用不需要建立数学模型的模糊控制实现闭环控制;在软件部分,采用汇编语言和C语言的混合编程实现算法和对主电路输出的控制。控制电路和控制软件的设计是整个系统的核心也是本论文的主要工作。 通过实验证明了系统原理的正确性。实验结果表明把ARM嵌入式处理器用于交流Buck-Boost实现数字控制不仅是可行的,而且具有良好的静、动态性能。数字控制电源已经成为电源发展的新方向,本课题结论对于数字控制电源提供了新思路。更多还原

【Abstract】 The present thesis mainly deals with the digital control of the embedded processor(ARM) applied to the Buck-Boost circuit to regulate alternating current(AC). It also covers the following aspects such as the structure of the AC regulating system, the controlling method and strategy, the design philosophy and research work of the controlling software and hardware, and their theoretical tests.Firstly, the author has analyzed the application of the Buck-Boost circuit to the direct current(DC),upon which the theoretical analysis on the application of the Buck-Boost circuit to the alternating current(AC) is based. By introducing the function, the mathematical relationship of the input and output voltage is deduced, which serves as the theoretical base for the digital control.In regard to the hardware, the author has designed a control circuit with a new type of Buck-Boost circuit as the major circuit topology and with the ARM embedded processor made the Philips as the core, as well the hardware system for circuit examination. Concerning the calculation, the author has adopted the blur control without the mathematical modeling to realize the closed circuit control. With regard to the software, the assembly language and C language are both adopted in calculation and the control of the main circuit. The design of the controlling circuit and software is the kernel of the system as well as of the present thesis. Experiments have been done to prove the validity of the principles.The results have proved that it is feasible to apply the ARM embedded processor to the Buck-Boost circuit. In addition, it has presented benign performances both statically and dynamically. As digital control represents the new trend in the study of current, the present thesis and the relevant results provide a new angle to digital control.更多还原
