PLS Model Based Control for the Tennessee Eastman Challenge Problem
The Tennessee Eastman (TE) challenge problem based on a Tennessee Eastman Company process has been widely used in process control studies. In practical situation it is not easy to deal with the multi-input multi-output (MIMO) control systems due to their complex and interactive natures. This article presents the application of a partial least squares (PLS) based PID (PIDPLS) control approach to the TE benchmark process for modelling and control. In this work, a decentralized plantwide control system design based on multiple single-input single-output (SISO) control loops for the TE process (McAvoy and Ye, 1994) is first tested. Then a simplified TE control structure is constructed from PLS modelling analysis. It is shown that the proposed PIDPLS algorithm can easily decompose the interactive nature of the system and automatically determine the control pairs in the latent space. Simulation results demonstrate the superior performance of the PIDPLS control algorithm as compared to the decentralized PID control system proposed by McAvoy and Ye(1994). In this case, the presented PIDPLS control approach can provide satisfactory regulation control performance as the dynamic matrix control (DMC) scheme.
