论文摘要
在本文中,提出了一个自适应观察者,用于多输入多输出(MIMO)离散时间线性时间流(LTI)系统。与现有的MIMO自适应观察者设计不同,所提出的方法适用于LTI系统的一般形式。此外,提出的方法将递归最小二平方(RLS)与协方差重置进行适应,以确保估计值是有界的,无论是否有任何激发条件,即使存在用于更新RLS中的错误的扰动项。为收敛和界定度提供了详细的分析,并提供了仿真结果,以说明开发理论的性能。
In this paper, an adaptive observer is proposed for multi-input multi-output (MIMO) discrete-time linear time-invariant (LTI) systems. Unlike existing MIMO adaptive observer designs, the proposed approach is applicable to LTI systems in their general form. Further, the proposed method uses recursive least square (RLS) with covariance resetting for adaptation that is shown to guarantee that the estimates are bounded, irrespective of any excitation condition, even in the presence of a vanishing perturbation term in the error used for updation in RLS. Detailed analysis for convergence and boundedness has been provided along with simulation results for illustrating the performance of the developed theory.
