Keeping in tune the global developments we are creating an institutional repository using DSpace Software (Digital Library Software). We are archiving institutional knowledge like, faculty papers, theses, and dissertations in PDF format at DSpace. Students can access this digital information anywhere in the campus.

| Abstract: | Instantaneous Optimal Control is used to obtain desired force from MR damper fitted to a seismically excited building. Excitation is considered when minimizing performance index, unlike in classical optimal controllers. Modified Bouc-Wen damper model and on-off voltage law is considered. Various forms of state weighting matrix are considered for controller design. IOC is compared with LQR/LQG and PON control. It yields reduction in: maximum peak interstorey drift; and generally in accelerations vis-a-vis LQR/LQG. IOCSF Riccati Matrix Type controller appears most effective, yielding: lowest maximum peak drift/acceleration and generally best storeywise drift control vis-a-vis PON/LQR/LQG; substantially lower peak accelerations vis-a-vis LQR/LQG. |
