Embodiment Construction
[0028] The purpose and effects of the present invention will become more apparent by referring to the accompanying drawings in detail of the present invention.
[0029] The predictive control method of the present invention is mainly applied to figure 1 The cement production firing system shown, the specific implementation method is as follows:
[0030] 1. Multivariate prediction model based on impulse response
[0031] The predictive control algorithm of the present invention adopts the impulse response non-parametric model of the characteristics of the controlled system as the internal predictive model. figure 2 The input-output relationship diagram of the variables is given, in which the coal feeding amount of the calciner, the coal feeding amount of the kiln head and the opening of the tertiary air valve are taken as the operating variables, the raw meal feeding amount is used as the disturbance variable, and the O2 content at the outlet of the top cyclone , the CO con...
