Decentralized Fuzzy-PID Based Control Model for a Multivariable Liquid Level System
Multivariable liquid level control is essential in process industries to ensure quality of the product and safety of the equipment. However, the significant problems of the control system include excessive time consumption and percentage overshoot, which result from ineffective performance of the tuning methods of the PID controllers used for the system. In this paper, fuzzy logic was used to t...
متن کاملOptimization of Reduction Settings and Inter-stand Tensions for Tandem Cold Mills using Genetic Algorithm
Cold rolling process is a complicated process which can be optimized by changing in variables and settings. This paper presents a set-up optimization system developed to calculate reductions and inter-stand tensions for each stand of a five stand tandem cold mill. The main objective in this optimization is minimization of power consumption. First, by using the analytical method, the equations ...
متن کاملMultivariable nonlinear predictive control of cement mills
A new multivariable controller for cement milling circuits is presented, which is based on a nonlinear model of the circuit and on a nonlinear predictive control strategy. Comparisons with previous LQ control strategies show improved performances with respect to an important source of perturbations of the circuit: a change of hardness of the raw material.
متن کاملSet-up optimization for tandem cold mills: A case study
This paper presents a set-up optimization system developed to calculate reduction for each stand of a four stand tandem cold mill installed at Cosipa plant, Brazil. This optimization system is composed of an initialization phase and an optimization phase. The initialization phase consists of a non-iterative calculation procedure, proposed as an alternative for the iterative algorithm presented ...
