论文摘要
引入了一个新的调整规则，用于线性主动干扰拒绝控制（ADRC），该规则与常用的带宽参数化设计相似，但闭环动力学类似，但反馈的增长较低。通过这种方式，控制器的噪声灵敏度降低，为在受噪声影响的应用程序中使用ADRC铺平了道路。事实证明，所提出的调整增益虽然植根于代数riccati方程的分析解决方案，但可以通过简单地将增益减半来从带宽参数化设计中获得。这建立了最佳控制和杆位设计之间的联系。
A new tuning rule is introduced for linear active disturbance rejection control (ADRC), which results in similar closed-loop dynamics as the commonly employed bandwidth parameterization design, but with lower feedback gains. In this manner the noise sensitivity of the controller is reduced, paving the way for using ADRC in more noise-affected applications. It is proved that the proposed tuning gains, while rooted in the analytical solution of an algebraic Riccati equation, can always be obtained from a bandwidth parameterization design by simply halving the gains. This establishes a link between optimal control and pole placement design.
