Covariance Control Using Closed Loop Modeling for Structures

Covariance Control Using Closed Loop Modeling for Structures1
Jianbo Lu and Robert E. Skelton2
Abstract
This paper presents a low order controller design method, using closed loop modeling
plus covariance control, with application to the benchmark problem in structural control
for the active mass drive system at the University of Notre Dame [1]. This method
nds a satisfactory controller by iterating between closed loop modeling and covariance
control. The closed loop modeling implies that the model used for model-based control
design is extracted from the feedback system of the last iteration
