This paper proposes a multi loop decentralized control strategy for the control of a wastewater treatment plant based on an Activated Sludge (ASP) model. The ASP is a described by means of a nonlinear model and results on a Two-Input Two-Output multivariable system. Even though advanced control strategies have been presented in the literature, the proposal… (More)

This paper analyzes optimal controller settings for controllers with PID structure. The analysis is conducted from the point of view of the operating mode (either servo or regulation mode) of the control loop and tuning mode of the controller. It is well known that, specially for optimization based settings, the performance of the control loop is defined in… (More)

This paper presents a generalization of the Internal Model Control (IMC) approach to feedforward control action generation. As is well known, one of the distinctive features of the IMC formulation is the possibility to distinguish between the nominal and uncertain situations. However the consideration of the presence of uncertainty for the feedforward part… (More)

The aim of this paper is to present a robust tuning method of two-degree-of-freedom (2DoF) proportional integral (PI) controllers for integrating controlled processes. This is based on the use of a model reference optimization procedure with servo and regulatory closed-loop transfer functions targets. The designer is allowed to deal with the… (More)

This paper presents an analytically deducted procedure for tuning two-degree-of-freedom proportional integral (PI) controllers for first-order-plus-dead-time (FOPDT) controlled process. The equations incorporate a design parameter, which relates the feedback control systempsilas time constant, with the controlled process time constant. The design procedure… (More)

In tasks of human supervision in industrial control room several generic disciplines such as the software engineering for the design of the computing interface and the human factors for the design of the control room layout come into application. From the point of view of the human computer interaction, to these disciplines it is necessary to add the… (More)

In this work, the Virtual Reference Feedback Tuning is applied to the control of a boiler plant benchmark. Only data (without any modelling step) was used to compute a series of PI controllers for both a decentralized and a complete multi-loop control strategies. When compared with other PI controllers, it was found that a better tuning of the controller… (More)

The aim of this paper is to present a robust tuning method for two-degree-of-freedom (2DoF) proportional integral (PI) controllers for inverse response controlled processes modeled by a second-order plus a right-half plane zero (SOPRHPZ) transfer function. This is based on the use of a servo and regulatory control closed-loop model reference optimization… (More)
