Artificial Neural Network-Based Gain-Scheduled State Feedback Speed Controller for Synchronous Reluctance Motor

Tarczewski, Tomasz; Niewiara, Łukasz; Grzesiak, Lech M. (sciendo, 2021-11-10)

This paper focuses on designing a gain-scheduled (G-S) state feedback controller (SFC) for synchronous reluctance motor (SynRM) speed control with non-linear inductance characteristics. The augmented model of the drive ...
Neural Network Contour Error Predictor in CNC Control Systems

Erwiński, Krystian; Paprocki, Marcin; Wawrzak, Andrzej; Grzesiak, Lech M. (2016-11-12)

This article presents a method for predicting contour error using artificial neural networks. Contour error is defined as the minimum distance between actual position and reference toolpath and is commonly used to measure ...
PSO based feedrate optimization with contour error constraints for NURBS toolpaths

Erwiński, Krystian; Paprocki, Marcin; Wawrzak, Andrzej; Grzesiak, Lech M. (2016-11-12)

Generation of a time-optimal feedrate profile for CNC machines has received significant attention in recent years. Most methods focus on achieving maximum allowable feedrate with constrained axial acceleration and jerk ...
