base identifier meaning in English

基标识符

An sm based identifier is presented to deal with the parameter identification problem for a class of parameter uncertain nonlinear dynamic systems with input nonlinearity . an smc algorithm is employed to ensure the global reaching condition of the sliding mode for the nonlinear system , and an identifier is designed to identify the uncertain parameters of the nonlinear system
论文的主要内容如下：针对一类相对于输入为非线性的系统，设计了滑模变结构控制器保证非线性系统的全局渐近稳定，在此基础上，考虑到系统运行在滑模面上时所具有的特点，提出了一种基于滑模变结构控制的参数辨识方法来辨识非线性系统的未知参数。
