根据台车式退火工艺制度,在软件平台上开发了L1级和L2级控制系统。其中,L1级的控制策略采用增量式PID算法,L2级的核心模型采用引入热电偶的三元模型。该控制系统模拟了台车式退火炉在各阶段的热过程,得到了炉内各元的温度场。另外,系统对升温转保温阶段进行了处理,通过两种方法保证了过渡过程的稳定性。 According to the trolley annealing process system, L1 and L2 control systems have been developed on the software platform. Among them, L1-level control strategy using incremental PID algorithm, L2-level core model using thermocouple introduced ternary model. The control system simulates the thermal process of the trolley annealing furnace at various stages and obtains the temperature field of each element in the furnace. In addition, the system to heat transfer to the holding phase, through two methods to ensure the stability of the transition process.
