【正文】 頻比控制，給出了完整的硬件電路設(shè)計和軟件程序流程設(shè)計。 1 SPWM 變頻調(diào)速系統(tǒng) 摘要 ：變頻調(diào)速是交流調(diào)速中的發(fā)展方向 。異步電動機(jī)的調(diào)速原理是研究控制算法的基石，因文首先介紹了異步電動機(jī)的調(diào)速特性，從而展開介紹 SPWM變頻調(diào)速的理論基礎(chǔ) .包括變頻調(diào)速控制思想的由來，控制方法的可行性。采用了 Intel8OC196MC十六位單片機(jī)作為控制電路的 CPU，采用該單片機(jī)的控制系統(tǒng)是本設(shè)計的硬件核心部分 。恒壓頻比控制 。 Abstract variable frequency speed control is the development direction of AC speed control system. Control principle of asynchronous motor is a cornerstone of control algorithm research, because the first introduced the speed characteristics of asynchronous motor, thus the theoretical basis of SPWM variable frequency speed regulation. Including the origin of VVVF control thought, the feasibility of control method. Control algorithm of variable frequency speed control there are many, constant ratio of voltage and frequency control algorithms currently used by most of the general inverter, give a plete hardware circuit design and software program flow design. Using the Intel8OC196MC sixteen bit singlechip microputer as a control circuit of CPU, control system using the SCM is part of the design of the hardware core. Keywords: inverter。 sinusoidal pulse width modulation: 8OC196MC single chip microputer. 2 目錄 第 1 章 緒論 變頻器的發(fā)展方向 ......................................................................... 1 發(fā)展的目的和意義 1 第 2 章 恒壓頻比控制的 SPWM 變頻系統(tǒng)的分析 變頻調(diào)速基本原理 ................................................................................ 2 變頻調(diào)速控制方式分析 ........................................................................ 2 SPWM 逆變技術(shù) ................................................................................... 4 控制信號的產(chǎn)生方
