CDC (Conference on Decision and Control) 2020: invited session on "Mechatronics"
The goal of this invited session, Mechatronics, is to bring together a diverse group of active researchers in the area of mechatronics and present to the community some of the most recent advances in the control techniques and observation algorithms to enhance the performance of a class of mechatronic systems. These contributed by authors from different countries across Asia, Europe, and North America. In particular, the six papers in this invited session share a coherent theme of control, estimation, and analysis of mechatronic systems.
We particularly invite contributed papers treating, but not limited to, the following aspects: In the first paper Beltran et al. present a recursive algorithm for the output regulation of the hysteresis remnant behavior described by Preisach operators. The hysteresis remnant behavior is the remaining memory of the output (of the actuator) when the actuation signal is set to zero. The study proves that the proposed algorithm guarantees that the output remnant converges to a desired value. The second paper, authored by Jeong and Chung, present nonlinear torque modulation and current controller of Permanent Magnet Synchronous Motors. The sliding mode disturbance observer is used in the study for velocity tracking. The study presents experimental results obtained from a motor and generator set to validate the performance of the proposed method. In the third paper, Strijbosch1 and Oomen develop a feedforward controller for hysteresis phenomena in piezo actuators using hybrid MEM- elements which can model a wide variety of elements that are memory dependent. The authors used a simple identifi- cation approach of a MEM-element capturing the hysteresis phenomena and a unique inverse allowing for an intuitive feedforward controller. The developed approachis success- fully applied to a piezo actuator. In the fourth paper, Khalil et al. design an observer-based fault detection approach based on the excitation signal to detect failures in multi- actuators-based motion systems. The authors consider the most common actuator faults such as actuator stuck failure, loss of effectiveness, and fatigue crack in the connection hinges. The proposed approach was tested experimentally. Ohno et al., the authors of the fifth paper, propos a novel adaptive design methodology for cutting force observer, con- sidering stage parameters variation. In the proposed method, stage mass, viscous friction, and the Coulomb friction of the moving stage are estimated. The proposed cutting force observer deals with the stage parameter variation by updating the observer with the identified parameters. The validity of the proposed adaptive observer is verified by simulation and experimental results. The sixth paper, authored by Al Janaideh et al., is focused on output-feedback control of a piezomicropositioning tube actuator with uncertain nonlin- earities. The paper proposed an extended high-gain observer to stabilize a class of precision motion systems with unknown hysteresis nonlinearties. The proposed approach was tested on a piezomicropositioning tube actuator.
