Optimal and robust feedback controller estimation for a vibrating plate

This paper presents a method to estimate the H2 optimal and a robust feedback controller by means of Subspace Model Identification using the internal model control (IMC) approach. Using IMC an equivalent feed forward control problem is obtained, which is solved by the Causal Wiener filter for the H2 optimal controller. The robust variant, called...

MIMO H2 optimal feedback controller estimation for a vi-brating plate using Subspace Model Identification

Adaptive Active Control algorithms, such as the well known Filtered-X LMS and Filtered-U LMS algorithms, often do not yield optimal performance in practise, due to finite length impulse response of the controller (Filtered-X) or convergence to a local minimum (Filtered-U). In addition, especially for the MIMO case, these adaptive controllers...
