In this paper, a model predictive control (MPC) method is proposed for three-level bi-directional DC-DC converter. The multiple optimized performances, including DC voltage steadiness and midpoint voltage balance, are achieved by building prediction model, establishing cost function and determining optimization process. Finally, Simulation results show high static/dynamic performances of the converter.
Urban deep foundation excavations are generally surrounded with dense buildings. So their working space is very narrow, especially when they are close to the foundations of adjacent buildings or structures in construction. Many scholars, engineers and technicians have already worked a lot in the displacement-controlling design of deep foundation excavations recent years, however, difficulty remains...
