在本文中,我们提出了一种混合的方法来识别线性动态系统的破坏加性,幅度有界的白色噪声。为了得到系统的估计,我们混合了来自预测误差估计和集员估计的信息。这种方法鲁棒的参数估计,使他们受益于预测误差和集成员的功能。所提出的估计技术表现出良好的性能上的一些模拟的例子,这是使用广泛的噪声源进行。
In this paper, we propose a mixed approach to identification of linear dynamic systems corrupted by additive, amplitude bounded white noise. To come up with an estimate of the system, we mix the information from a prediction error estimate and a set membership estimate. This approach robustifies the parameter estimates, so that they benefit from both the prediction error and the set membership features. The proposed estimation technique shows good performance on a number of simulation examples, which are performed using a wide range of noise sources.
