Hybrid systems model and simulation for multi-cranes energy-saving system
多起重机节能混杂系统模型及其仿真*

To ensure the equipments work in the trouble free operation and a good energy saving effect, constructed an equivalent circuit model for multi-cranes common DC bus energy-saving systems. By introducing the hybrid dynamic systems theory, estabilished the power grids rectifier model based on hybrid automata, and extended an activity cycle diagram (ACD) to build models for hybrid systems. Based on this hybrid ACD, established a controlled power source model. Finally, simulated the power and voltage of the common DC bus to verify the reasonableness of the proposed model. The main contribution of this paper was to provide a simulation benchmark of the multi-motor energy-saving system for further research.
