Semi-active Model Predictive Control for 3rd Generation Benchmark Problem Using Smart Dampers

This paper presents a semi-active strategy for model predictive control (MPC), in which magneto-rheological dampers are used as an actuator for use in reducing nonlinear seismic response of high-rise structures. A multi-step predictive model is developed to estimate seismic performance of high-rise structures, considering account effects of nonlinearity, time-variability, model mismatching, disturbances, and uncertainty of controlled system parameters by the predicted error feedback in the multi-step predictive model. Based on the predictive model, a Kalman-Bucy observer suitable for semi-active strategy is proposed to estimate the state vector from acceleration and semi-active control force feedback. Main advantages of the proposed strategy are its inherent stability, simplicity, on-line real-time operation, and its ability to handle nonlinearity, uncertainty, and time-variability properties of structures. Numerical simulation of the nonlinear seismic responses of a controlled 20-story benchmark building are conducted and results are compared to those of other control systems. Results show the developed semi-active strategy can efficiently reduce nonlinear seismic response of high-rise buildings.
