DESIGN METHODS AND TUNING OF BILINEAR PROPORTIONAL-INTEGRAL-PLUS CONTROLLERS

摘要

This paper describes the advantages of extending the existing linear philosophy of proportional-integral-plus (PIP) control to a bilinear case. Investigation of the quasilinearisation, design and tuning procedures together with an additional quasilinearisation parameter are presented. The role of the quasilinearisation parameter and the potential improvements in closed loop performance are demonstrated via simulation studies using a system similar to that found in high temperature furnaces.
