Abstract:
In order to promote the construction of high performance intelligent seismic test platform, realize the intelligent upgrade and optimization of shaking table control algorithm, a deep learning controller framework of shaking table based on LSTM(Long and Short-term Memory Network)was proposed in the paper. The feasibility and effectiveness of LSTM controller was verified by training and simulating the input-output relationship of three-variable controller. Considering the limitation that LSTM relies on complete and continuous trajectories to preserve memory, a method of processing real-time feedback signal based on LSTM closed-loop control was proposed, which helps the LSTM controller to avoid the loss of past memory when receiving real-time feedback signals by storing the hidden layer state“h”and the long-term memory state“c”separately. The simulation results shown that the deep learning controller can effectively imitate the control performance of the three-variable algorithm and reproduce the time-history curve of seismic acceleration wave through the training method of supervised learning, which indicated that the deep learning controller has enough potential in dealing with nonlinear control problems. © 2022 Science Press.
