On neural network based online tuning of rolling mill drive armature current Pl-controller parameters

Development of the method for joint operation of neural-network tuners for current and speed

“…Our study is continuation of a larger study into development and application of a neural-network tuner in the control systems of a direct current electric drive [9,10]. The aim of further research is to apply a neural-network tuner for the more complex systems of electric drive control.…”

“…PhD, Associate Professor* Е-mail: strondutt@mail.ru At the same time, the authors have already designed neural-network tuners for current controllers [9] and speed regulators [10], which operate in real time and do not require a model of the control object. Effectiveness of the tuners was tested in situations when only one of them was functioning during experiment.…”

“…In accordance with the method proposed in paper [11], the tuner of speed control circuit employs an artificial neural network with the structure 2-7-1, the tuner of current control circuit -5-14-2. A description of the rule bases of tuners is given in [9].…”

“…Neural-network tuners are also implemented in the form of S-functions. A more detailed description of the model is given in [9].…”
