三、参数估计技术 通过结构识别,模型结构已知,但还有一些参数是未知的。有些参数虽然可以从被控过程的运动规律出发来确定,但是由于在结构识别时用了一些简化的假定以及实际过程与环境的关系的复杂性,使得那些参数还需用实际过程的实验数据来确定。总之,参数估计是系统辨识的一个很重要的部分。这也是系统辨识中研究得最多,成果最丰富的
Third, the parameter estimation technology through structural recognition, the model structure is known, but there are still some parameters are unknown. Although some parameters can be determined from the law of motion of the controlled process, due to the complexity of the relationship between the actual process and the environment due to some simplified assumptions in the structure identification, those parameters need to be obtained from the experimental data of the actual process determine. In short, parameter estimation is a very important part of system identification. This is also the most studied and most productive system identification
