在超临界热力机组上利用多变量自回归模型,实现了一种实用的新式最优控制。控制是依靠在常规PID控制基础上对机组系统特性的辨识和对常规模拟控制作修正的数字控制来实现的。用机组实际试验结果详细地叙述了实现辨识与控制的过程,证明这种新型控制器比常规PID控制器远为优越。
Using multivariable autoregressive model in supercritical thermal power unit, a practical new optimal control is realized. Control is based on the conventional PID control based on the identification of the unit system characteristics and the conventional analog control to amend the digital control to achieve. The actual test results of the unit are used to describe the process of identification and control in detail. It is proved that the new controller is far superior to the conventional PID controller.
