Fuzzy Identification on Inverse Dynamic Process of Steam Temperature Object of Boiler

It is crucial to establish the inverse dynamic process model of thermal system on research and application of the inverse dynamic process of thermal system.A method and result of on-line fuzzy identification on the inverse dynamic process model of steam temperature of boiler was reported.The method partitions the input data space of the inverse dynamic model into some local regions by the clustering and competitive learning algorithms,then fuzzy rule based the inverse dynamic process is built for each local regions by the recursive least-square identification algorithm(RLS),and the inversion of system input process is actualized by the adaptive fuzzy inference.The simulation results show that the established inverse dynamic model has good self-adaptation ability and on-line traceable ability to time variant steam temperature object.Through the on-line identification of inverse dynamic process of steam temperature object,it is possible to acquire appropriate controlling process and ensure the system's temperature output to arrive at the set value according to reference path.
