文中基于MATLAB/RTW,设计了一种根据PID控制器及LQR算法的直流调速控制系统,通过PCI-1711数据采集卡与MATLAB/RTW模块相结合,建立直流电机调速实时控制模型。利用MATLAB/RTW的实时开发环境,生成可执行的代码和执行实时仿真,利用RTW将模型文件转化为通用实时代码格,这种代码格式具有结构紧凑、灵活、执行速度快等优点从而大大提高了系统开发的可执行性,将传统的直流调速控制系统开发过程简化。该系统稳定性高,灵活性强,在同类设计中具有一定的独创性,并且有一定的实际应用价值。

This article designs a DC speed real-time control system based on MATLAB/RTW and PID, LQR algorithm, through a combinati（m of MATLAB/RTW and PCI-1711 data acquisition card module it establishes a model of DC motor speed control real-time system. By using the development environment of MATLAB/RTW, it generates executable code and executes real-time simulation. Converting model-files into universal real-time code in RTW, it has the advantages of compactedness, flexibility faster- excmtedas, therefore, it improves the performability of system development, and simplifies the development process of the traditional DC speed control system. This system has high stability, flexibility, and in the similar design it has a certain degree of originality and also practical value.
