摘要：

文中针对变频技术存在的缺陷,提出了一种基于dSPACE的脉冲阻塞式交交变频新思路。系统利用RTW对搭建的阻塞式交交变频系统数学模型进行代码生成,用于实现基于dSPACE的斩波调压控制策略。通过ControlDesk软件平台对实验中的参数和变量进行访问更改,实现了变频调压的目的,并在MATLAB 2011a环境下对变频系统进行了仿真。仿真与实验结果和理论相一致,验证了该系统控制策略的正确性及可行性,同时也为工业现场变频调速系统的设计与应用提供了依据。

Abstract:

In order to remedy the defect of frequency conversion technology, a new idea of pulse blocking AC frequency conversion based on dSPACE was proposed. The RTW was used to generate code for the mathematical model of the constructed blocking AC frequency conversion system, which was used to implement the dSPACE-based chopping voltage control strategy. The ControlDesk software platform was used to change the parameters and variables in the experiment, and the purpose of frequency conversion voltage regulation was finally realized. The frequency conversion system was simulated in the MATLAB 2011a environment. The simulation results were consistent with the experimental results and the theory, which verifid the correctness and feasibility of the control strategy of the system, and also provided the basis for the design and application of the industrial field variable frequency speed control system.

Key words: AC frequency conversion, dSPACE, ControlDesk, pulse blocking type, PWM control, voltage regulation and frequency modulation, MATLAB
