AI总结:

针对离散时间线性时不变系统,提出利用含噪输入输出数据直接综合动态输出反馈控制器的方法,以实现给定二次供给率下的耗散性或$H_2$性能,方法基于线性矩阵不等式且无保守性。

摘要:

本文针对离散时间线性时不变系统,提出了动态输出反馈控制器综合方法。综合目标要么是相对于给定二次供给率实现耗散性,要么是达到给定的$H_2$性能水平。假设系统动态的自回归模型未知,除了不属于性能通道的噪声扰动项。相反,我们有一个输入和输出的记录轨迹,该轨迹可能受到未知但有界扰动的污染。方法以由标量变量参数化的线性矩阵不等式的形式表述,而在无噪声情况下它们简化为线性矩阵不等式。在所考虑的设定下,综合过程是非保守的。

英文摘要:

In this paper we propose dynamic output-feedback controller synthesis methods for discrete-time linear time-invariant systems. The synthesis goal is either to achieve dissipativity with respect to a given quadratic supply rate, or to achieve given $H_2$ performance level. It is assumed that the autoregressive model of system dynamics is unknown, expect for the noisy disturbance term which is not part of the performance channel. Instead, we have a recorded trajectory of inputs and outputs which can be corrupted by an unknown but bounded disturbance. Methods are formulated in terms of linear matrix inequalities parametrized by a scalar variable, while in noiseless case they reduce to linear matrix inequalities. Within the considered setting, synthesis procedures are non-conservative.
