Identification and control of a laboratory-scale prototype for crushing copper

Abstract:

Ecuador is a small country located in the northwestern region of South America. Colombia this limited to the north, south and east by Peru and west by the Pacific Ocean. Its area is 283,561 Km2, is the fourth smallest country in South America, is a country rich in mineral resources such as copper. The presence of wealth and openness for your exploitation (copper) through national and multinational companies has allowed increasing interest to specialize and train students in these areas in the country. The actual demand for specialization and innovation in this area, has made students UNL (National University of Loja), develop a prototype laboratory scale of the first copper process as is the crushing as that is where it consumes about 50% of the total energy which deals in obtaining copper. This prototype developed with SolidWorks® and AutoCad® is jaw type, based on mark Retch of fabrication German with the respective adjustments such as adding an extra side drum as a counterweight. For offline control we require several proposals as PID controllers (Proportional, Integral and Derivative), MPC (Model of pbkp_redictive control), LQR (Lineal Quadratic Regulator) and Linear Observers with MATLAB®, and real-time control of Arduino® card for easy programming and low coste.
