Digital active optimal control of steel structures�D

�´˜^�i‰p�j�F
Concept of a digital-type active optimal control of steel structures is studied especially on the following two points ; that is, (1) improve of calculation time using complex modal analysis and (2) evaluation of an effect of control parameters. Since the state equation of control in a discrete-time system contains a matrix exponential function, which gives a large defect on the calculation time and on the stability of solution, orthogonal technic based on the complex modal analysis is used, and it gives a successful result. Control state of the system is strongly influenced by the weight functions, which appears in the Hamilton of Pontrjagin's maximum principle, the parametric study is provided on the e
