The semi-active algorithms used are the linear quadratic regulator (LQR) associated with the clipped optimal algorithm, an algorithm based on a prediction model and a dynamic inverse model using nonlinear autoregressive exogenous (NARX)-type artificial neural networks, and a decision-making algorithm based on fuzzy logic.
Additionally, the performances of the proposed semi-active algorithms are compared to those of passively used control devices.
The results show response value reductions exceeding 50% for all the semi-active control strategies, which con...
