2、炉温自校正 PID 控制系统设计 II ABSTRACT This paper adopts recursive least square method to research how to control the experimental boiler temperature and uses MATLAB to program and simulate. The further research and analysis are made on the basis of system simulation results, The results show that when adopti
3、ng the self-revised PID controller, the system can adapt the complex working conditions and the controller can select the PID parameters automatically. Morever, it has solved the difficult problem of setting large delay experimental boiler system PID parameters. In order to make the system more accurate, this paper adopts the estimation algorithm of recursive least-square method with forgetting factor.
