FLC -case A is based on Mamdani's reasoning methods, developed using Fuzzy Logic Toolbox [9] and integrated into Matlab Simulink dynamic model of BC, which is presented in [10]. In the process of fuzzification, the universe of discourse for linguistic variable e is mapped in the [-1, 1] interval and divided into 4 fuzzy sets: negative (N), negative small (NS), zero (ZE) and positive (P).…”

The paper presents a control strategy for the system of belt conveyors with adjustable speed drives based on the principle of optimum energy consumption. Different algorithms are developed for generating the reference speed of the system of belt conveyors in order to achieve maximum material cross section on the belts and thus reduction of required electrical drive power. Control structures presented in the paper are developed and tested on the detailed mathematical model of the drive system with the rubber belt. The performed analyses indicate that the application of the algorithm based on fuzzy logic control (FLC) which incorporates drive torque as an input variable is the proper solution. Therefore, this solution is implemented on the newvariable speed belt conveyor system with remote control on an open pit mine. Results of measurements on the system prove that the applied algorithm based on fuzzy logic control provides minimum electrical energy consumption of the drive under given constraints. The paper also presents the additional analytical verification of the achieved results trough a method based on the sequential quadratic programming for finding a minimum of a nonlinear function of multiple variables under given constraints

“…In a typical operation, the average mass per unit length of a conveyor is a large value, bigger than about 50% of the belt's q max , and so, usually, ∑ N x i=0 q(i, n)/N x 1 kg/m [11]. Therefore, generally, the power used by the conveyor is more sensitive to ϕ 2 than ϕ 1 , i.e., S P ϕ 1…”

Abstract:As electricity prices continue to rise, the increasing need for energy management requires better understanding of models for energy-consuming applications, such as conveyor belts. Conveyor belts are used in a wide range of industries, including power generation, mining and mineral processing. Conveyor technological advances are leading to increasingly long conveyor belts being commissioned. Thus, the energy consumption of each individual belt conveyor unit is becoming increasingly significant. This paper proposes a generic energy model for belt conveyors with long troughed belts. The model has a two-parameter power equation, and it uses a partial differential equation to capture the variable amount of material mass per unit length throughout the belt length. Verification results show that the power consumption calculations of the newly proposed simpler model are consistent with those of a known non-linear model with an error of less than 4%. The online parameter identification set-up of the model is proposed. Simulations indicate that the parameters can be identified successfully from data with up to 15% measurement noise. Results show that the proposed model gives better predictions of the power consumed and material delivered by a long conveyor belt than the steady-state models in the current literature.

“…Zbog dužine ovih tračnih transportera posebno su zahtevni procesi pokretanja, u toku koga pogon mora da razvije potreban, ali stalan moment u toku vremena polaska. Navedeni zahtevi mogu da se ostvare sa pogonima koji omogućavaju kontinualnu kontrolu brzine, zbog čega se novi pogoni na tračnim transporterima grade sa pogonima sa asinhronim motorima čija se brzina može kontrolisati [23].…”
