Multiple Model Approach for CSTR Control

摘要

A method for combining multiple local models to describe a nonlinear system. The local modelweights are based on the linear interpolation of the current operating point from the closest localmodel operating points defined as the filtered value of the current process input. This local modelingmethod can be used to describe systems with changing system gains and dynamics, as well as inputmultiplicity. A case study for a benchmark CSTR reactor is presented. Local linear models are used tosynthesize IMC based PID controllers.
