Title:
PLANT CONTROLLING DEVICE AND METHOD, THERMAL POWER PLANT, AND ITS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/102269
Kind Code:
A1
Abstract:
A control device which learns a model input creating method for achieving a model
output target value by using a model used for simulating the characteristics
of a controlled system and creating an operation signal according to the learning
results. The measurement signal of the controlled system determines the model
output target value for achieving the operation target value. The control device
comprises a model for predicting the value of a measurement signal generated
when an operation signal is given to a controlled system, a function of learning
a method of creating a model input so that the model output can reach a target value,
a function of determining an operation signal given to the controlled system
according to the results of the learning, a database for storing the limit value
of a preset measurement signal, an external input interface for capturing the
measurement signal of the controlled system, a measurement signal database
for storing the value of the captured signal, and a function for determining the
initial value of the model output target value by using the result of the computation
of at least one of the average value, the maximum value, and the minimum value of
the stored measurement signal and the limit value of the measurement signal.
