This algorithm employs the digital state-space equation to discretize the continuous dynamical equation of motion, and named discrete instantaneous optimal control method. Based on the Lyapunov stability method, a procedure to obtain a discrete stable weighting matrix is developed. To demonstrate the precision and the efficiency of the proposed control algorithm an 8-story shear-type building frame equipped with one active mass damper/driver (AMD) mechanism is used. Behavior of different weighting matrices is also examined.           }, keywords = {Active control,instantaneous optimal control,digital state-space equation,discrete stable weighting matrix,active mass damper/driver}, url = {https://ijstc.shirazu.ac.ir/article_792.html}, eprint = {https://ijstc.shirazu.ac.ir/article_792_dad635c2d1168d9a0357304e472d89fc.pdf} }
