自动控制系统频域分析的GUI仿真设计

频域分析法是线性自动控制系统的一种图形化分析法,用于分析系统的动态性能和稳态性能。利用Matlab/GUI界面设计工具与M文件编程结合,设计了自动控制系统频域分析的演示界面。该界面可进行系统参数设置,显示系统开环传递函数,绘制相应的对数坐标图,便于观察系统的组成或参数变化对系统性能的影响,能够满足课堂教学演示与课外仿真实验。

Automatic control system for GUI simulation design of frequency analysis

Frequency domain analysis method is a kind of linear automatic control system for the graphical method, is applied to the analysis of system dynamic performance and steady-state performance.by using the Matlab/GUI interface design tools and programming combined with M file,design the demo interface for automatic control system for frequency domain analysis. The interface can set parameters of system, display open loop transfer function of system, map corresponding logarithmic coordinate, observe the effect of system parameter or performance changes easily, can satisfy the presentation of class teaching and extracurricular simulation experiment.
