Optimal modal controller design by entire eigenstructure assignment
IEE Proceedings D: Control Theory and Applications
A computationally simple sequential algorithm for designing an optimal modal controller is presented. The approach is capable of systematically calculating a set of appropriate weighting matrices for the cost functional in the quadratic performance index, so that the resulting optimal control law would not only minimise the cost functional, but also place the eigenspectrum of the closed-loop system at some predefined locations.
