【正文】 SPWM變頻調速系統(tǒng)摘要：變頻調速是交流調速中的發(fā)展方向。異步電動機的調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的調速特性，控制方法的可行性。變頻調速的控制算法也有許多，目前大部分通用變頻器所采用的控制算法——恒壓頻比控制，給出了完整的硬件電路設計和軟件程序流程設計。采用了Intel8OC196MC十六位單片機作為控制電路的CPU，采用該單片機的控制系統(tǒng)是本設計的硬件核心部分。關鍵詞:變頻器。恒壓頻比控制。正弦波脈寬調制:8OC196MC單片機。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。 constant ratio of voltage and frequency control。 sinusoidal pulse width modulation: 8OC196MC
