In order to meet the beam commissioning requirements of HEPS, a new high level application (HLA) development framework was designed and named Pyapas. The new framework adopts a model-based control strategy, a double-layer physical model module is designed for online calculation, which can address complex physical parameter tuning issues. To facilitate physicists in beam commissioning and research, the new framework is designed based on physical quantities,, which can be more intuitive in the commissioning process for measuring parameter analysis. And Pyapas also uses modular design to reduce development time. In March, 2023, HEPS began beam commissioning work of Linac. With the help of the HLAs based on physical quantities, we quickly found the appropriate working mode and achieved full-line beam pass-through. The report will detail the design concept and features of Pyapas. ER -
