Abstract

SANDOVAL RUIZ, Cecilia E.; VELAZCO S., Katerine C.  and  DIAZ P., José Gregorio. Optimum control criteria for an electric driver for dynamic systems. Ing. Investig. [online]. 2008, vol.28, n.2, pp.66-71. ISSN 0120-5609.

This work was aimed at optimising control parameters for variable speed control and post-tensioning torque by controlling the current of DC motors forming part of a dynamic system (in a paper-making production line) by designing controllers based on absolute value and optimal symmetry criteria. A mathematical model representing an electric drive system for controlling DC motor speed and torque in a paper-rolling system was defined, a control algorithm adjusting the parameters was designed and an electric drive system simulated. The methodology consisted of a literature search and a field study for defining the model and establishing the parameters to be simulated, thereby presenting an analytical and descriptive project. The results led to observing the efficiency of the controllers so designed and the overall drive system for which speed and current (power) continue being the reference signal, leading to the conclusion that the criteria selected for control design were suitable and representing an input in developing applications for monitoring dynamic electric drive systems.

Keywords : optimal control; absolute value criteria; symmetric optimum; DC motor.
