Set up the environment variable ROO-DEV in your system settings, which should point to the bootstrap folder within the Roo project.
在您的系统设置中建立环境变量 ROO-DEV，该变量应指向 Roo 项目中的引导文件夹。
At first, through analysis of the system performance and the mathematics matrix of STATCOM, we introduced the voltage of the point where STATCOM jointed in the system as state variable.
首先，通过对系统性能以及STATCOM数学模型的分析，对原有数学模型进行了数学推导引入了STATCOM接入点的电压偏差作为控制变量。
For this point, many advanced control theories, such as adaptive control and fuzzy control, have been applied to variable structure system to reduce the chattering.
为了解决这一问题，许多其他的先进控制技术如自适应控制、模糊控制等也被综合应用到滑模变结构控制系统的设计中。
