Generalised optimal active control algorithm for seismic-resistant structures with active and hybrid control
by Franklin Y. Cheng
International Journal of Computer Applications in Technology (IJCAT), Vol. 13, No. 1/2, 2000

Abstract: The paper presents several optimal control algorithms including Riccati and instantaneous algorithms (ROAC and IOAC), generalised optimal control algorithm (GOAC), along with state control and state-slope control gain matrices. The strength and weaknesses of these algorithms are assessed and illustrated with numerical examples. It is concluded that GOAC is better than ROAC and IOAC in performance and that hybrid control is more effective in reducing structural response than active or passive devices only. Selection of state control or state-slope control gain matrix depends on the characteristics of the passive device.
