现场控制

In addition to these, a system identification computer program for the chain grate stoker was developed as well. After that, the system identification techniques based on PRBS and program was applied to an industrial-scale boiler. Practice shows that this method is easy and feasible. It could provide the theory model for the design and upgrading of the boiler's control system.
