Abstract
The article discusses the methodology for constructing an automatic control system for the feed module of the cutting tool for lathes in the presence of input saturation. The presence of the saturation function is due to restrict unwanted movements of the feed module actuator. The generator for periodic signals, the hyperstability criterion, L-dissipativity conditions and an implicit reference model are used as the solution methods for structural synthesis of the control system. At the stage of simulation, the functioning quality of the developed control system is illustrated.
Highlights
One of the most important problems of the modern theory and practice of automatic control is the problem of developing regulators for tool feed electric drives of the metal-cutting machines for processing non-circular parts ([Nikolsky, 2012], [Nikolsky, 2016], [Li, Li,1992], [Yurkevich, 2001])
The distinctive feature of this method is the presence in the control system main loop of the generator for periodic signals which is capable to reproduce any cyclical signals in order to track and/or parry them ([Hara et al, 1988], [Yao et al, 2013], [Ishii, Yamamoto, 1998], [Jiang et al, 1995], [Ramos et al, 2020], [Nikolova, 2019], [Toujeni et al, 2020], [Alsubaie et al, 2018], [Ma et al, 2020], [Ghosh, Paden, 2000])
We propose the nonlinear regulator for repetitive control system of mechatronic module for cutting tool in the presence of input saturation
Summary
One of the most important problems of the modern theory and practice of automatic control is the problem of developing regulators for tool feed electric drives of the metal-cutting machines for processing non-circular parts ([Nikolsky, 2012], [Nikolsky, 2016], [Li, Li ,1992], [Yurkevich, 2001]) Such systems are characterized by the cyclical nature of the reference action, which determines the desired movement of the cutter. We propose the nonlinear regulator for repetitive control system of mechatronic module for cutting tool in the presence of input saturation
