A new approach to designing plantwide control systems that is based on a linear dynamic process model and output optimal control is extended in this paper. The design of a plantwide architecture is split into four stages, and the results from one sta

Volterra series models are attractive for use in model-based control of nonlinear processes because they are direct extensions of linear impulse response models commonly used in process control. However, a limitation in their use is the fact that hig

This paper presents an intuitive on-line tuning strategy for linear Model Predictive Control (MPC) algorithms. The tuning strategy is based on the linear approximation between the closed-loop predicted output and the MPC tuning parameters. By direct

We present a complementary approach to real-time optimization (RTO) for maximizing the operating profit of an existing chemical plant without requiring a model-updating procedure, which is cumbersome and which may not necessarily improve the model. T

Batch and semi-batch reactors are usually highly nonlinear and involve complex reaction mechanisms. Often, the lack of rapid direct or indirect measurements of the properties to be controlled makes the process control task very difficult. It is the u
