Stochastic independent modal-space control of distributed-parameter systems

  • 55 Accesses


This reply is concerned with a comment by Turner and Chun on the solution of the matrix Riccati equation used in Ref. 1. Whereas the technique suggested by Turner and Chun may have some numerical advantage over Potter's method in the case of coupled large-order systems, the advantage is minimal when the independent modal-space control method is used.
