State based adaptive feedback - / feedforward - pid - regulator (pid - control unit)

摘要

Method for automatically switching of an adaptive pid - regulator (pid - control unit), comprising the steps of:Defining a model amount, a plurality of individual models mod_i, .. Mod_n , wherein each of the models of the controlled (controlled) process, and contains a plurality of parameter values;Define a plurality of model part amounts within the model amount; wherein each of the model part amounts of a state parameters s_i having a process variable input and a defined allowed, under which the models are grouped, as well as a plurality of start parameter values which represent the model part quantity;Determining the state parameter s_i , and updating of the pid - controller with the plurality of beginning parameters values, which belong to the state parameter;Evaluating each of the models, in the model part quantity mod_i, .. Mod_j in accordance with the state parameters s_i and calculating a square error of the model for each model;Determining an adaptive parameter value as a function of the square error of the model; andUpdating of the pid - controller in response to the adaptive parameter value.
