Modeling and control for DEDS and hybrid system.
Focus on lifecycle management of manufacturing system based on hybrid system control.
1) The issue of coordination manufacturing under the change of machine lifecycle indicators was studied earlier, which was supported by the Natural Science Foundation of China and other funds. The relevant systems for Shanghai Baosteel/ Honeywell were developed for addressing the steel rolling scheduling problem.
2) The machine lifecycle state estimation problem was studied. Due to the fact that there exists a complex carry-over effect between equipment setting and quality characteristics and the latter may gradually drift over the production runs in the chemical mechanical polishing process, the R2R control of wafer fabrication processes with drifts was studied even in the presence of metrology delay, and IEEE journal etc. articles were published;
3)The reconfigure of the ship's power grid and its integrated power system are studied, including the multi-scale modeling and reliable control of the integrated power system. The research is devoted to the optimization modeling and real-time calculation of grid reconfiguration and real-time evaluation of reliability for the mission-critical tasks.
