In this paper, we investigate a cooperative model predictive control for distributed photovoltaic (PV) power generation systems. A two-level control strategy is proposed. The upper level is cooperative control and the lower level is model predictive control based on dynamic matrix control. The proposed control strategy not only makes all the distributed PV generators converge and operate at the same...
In recent years, there have been an increasing number of photovoltaic (PV) generators integrated into the modern distribution power network. However, the introduction of a large number of PV units could have a negative impact on the distributed PV grid-connected power generation systems, such as polluting the grid, and causing grid instability, even resulting in the voltage collapse if the relevant...
Wafer stage control system of step-scan lithography is a typical dual-stage system. Fine actuator ensures the high tracking precision and coarse actuator makes large-stroke movement to keep the fine actuator is not closed to saturation. PQ method is an effective technique for transforming a DISO system to two SISO systems. Two correlative controllers are designed for the parallel SISO systems which...
