Model-predictive-control method with disturbance estimation by equivalent-input-disturbance approach for wind-induced vibration

Abstract

This paper presents a new active control system that combines the equivalent-input-disturbance (EID) and the model-predictive-control (MPC) methods. The MPC method predicts system responses and calculates an optimal control force. An accurate response prediction necessitates disturbance information. However, wind loads cannot be directly measured. This paper uses the EID approach to estimate the wind loads and combines it with the MPC method. The simulation results demonstrated that the EID approach significantly improves the control performance of the MPC method.
