Abstract
The invention provides a dynamic system gain estimation method based on a historical data steady-state value, and the method comprises the steps: firstly, dividing an input time sequence and an outputtime sequence into short data segments through employing a linear segmentation representation method, and finding out data segments with input and output being in a steady state at the same time; calculating input and output steady-state values from the data segment under the steady-state condition; elements, in the steady-state values, associated with the same steady-state gain in statistical significance are found, the elements are divided into one group, the steady-state gain of each group is estimated, and interval estimation of estimation parameters is given. According to the method, theinput and output steady-state values can be automatically found in the historical data sample, a plurality of steady-state gains under different working conditions can be accurately and effectively estimated, verification is carried out through a visualization method, and the problems that the time consumption for searching the steady-state values is long, the steady-state values are easily influenced by nonlinearity and the steady-state gain change is difficult to detect are solved.
Description
technical field [0001] The invention relates to a dynamic system gain estimation method based on historical data steady state value. Background technique [0002] Steady-state gain is the fundamental information needed for dynamic system control, diagnostics, and optimization. The characteristics of dynamic systems in the real-time operation stage are often different from those in the design stage. Therefore, the steady-state gains obtained in the phase of designing a dynamic system are usually not available in the real-time operation phase and must be updated. In addition, many dynamical systems are inherently nonlinear, so their steady-state gains tend to change as the dynamical system rests at different operating points. [0003] At present, two methods are commonly used to estimate the steady-state gain: a practical method is to obtain the steady-state values of the input and output of the dynamic system through some special tests to estimate the steady-state gain. ...
