The Inferential predictive control method of coal mill ...

2015-11-29  The Inferential predictive control method of coal mill Abstract: This paper presents the shortcomings of traditional PID method in coal mill control, such as multivariable coupling, nonlinearity and large-time delay, and give a new method to solve the problems. Firstly, the principles of coal mill is presented, and a coal mill model is established.

Nonlinear Modeling and Inferential Multi-Model Predictive ...

Fuel preparation is the control bottleneck in coal-fired power plants due to the unmeasurable nature or inaccurate measurement of key controlled variables. This paper proposes an inferential multi-model predictive control scheme based on moving horizon estimation for the fuel preparation system in coal-fired power plants, i.e., the pulverizing system, aimed at improving control precision of ...

Derivation and validation of a coal mill model for control ...

2012-5-1  Sensors for coal flow measurement from the mill to the furnace have become available on the market (Blankinship, 2004, Department of Trade and Industry, 2001, Laux et al., 1999).Unfortunately the equipment tends to be expensive and requires frequent calibration; thus it cannot be used directly for control purposes at this time of writing.

Nonlinear coal mill modeling and its application to model ...

In order to demonstrate one of these use cases a nonlinear model predictive control (NMPC) application was developed based on the coal mill model and the performance of the NMPC was compared to a conventional coal mill control strategy for tracking load change references and for rejecting disturbances caused by variations in coal moisture.
