The need for economic efficiency and safety has driven the development of large and complex chemical plants. Due to the presence of interactions, controlling such plants are often difficult. This paper aims to address this issue by developing a networked-based process control approach. In this framework, a plantwide process is modeled as network of process units which is controlled by a network...

Chemical processes often exhibit a heterogeneous character and often have a highly complex behavior. In this work, a benchmark problem for hierarchical hybrid plantwide control is presented. The considered chemical process consists of coupled batch and continuous reactors. For this process, a hierarchical solution will be motivated. In order to compensate most disturbances, time-variant paramet...

High performance processes should operate close to design boundaries and specification limits, while still guaranteeing robust performance without design constraint violations. Since design chemical process is operating close to tighter boundaries safely; much attention has been devoted to integrating design and control, in which the design decisions, dynamics, and control performance are consi...

An important issue for optimal operation and plantwide control is to find the degrees of freedom available for optimal operation. A previously published systematic approach to determine the steady state degrees of freedom is expanded to take into account the active charge as a possible degree of freedom in cyclic processes. Additional degrees of freedom related to the composition of the circula...

In order to design a process that operates close to tighter boundaries safely, much attention has been devoted to the integration of design and control, in which the design decisions, dynamics, and controlled performance are considered simultaneously in optimal fashion. However, rigorous methods for solving design and control simultaneously meet challenging mathematical formulations which becom...

Industrial plants dedicated to ethanol production have a large number of interrelated processes and operations with nonlinear dynamics, requiring process control design method considering plantwide aspects techniques application, as fuzzy logic, overcome disturbance effects on performance. In this work, in an plant were investigated order propose system improve the keep productivity. The was se...

Consider the generalized control design problem in Figure 1. Here, the objective is to design the controller K, which, based on the measurements y, computes the inputs (MVs) u such that the controlled outputs (CVs) z are kept close to their desired setpoints, in spite of unknown disturbances, varying setpoints and measurement noise(w). However, note that it assumed that we know what to measure ...
