“…The head-positioning control system is one of the most widely used sampled-data positioning control systems all over the world and essential to infrastructure for our advanced information society. Moreover, the control system and characteristics of the controlled object in the head-positioning control systems are similar to other precise positioning systems such as a galvano scanner, or a linear X-Y stage (Seki and Iwasaki, 2014;Sakata et al, 2014). Therefore, to show the validity of the proposed method, we employ the head-positioning system of HDDs as a textbook example (Franklin et al, 1998).…”

“…The wide availability of inexpensive microprocessors has made sampled-data control systems very popular for positioning control in mechatronic products (Hirata et al, 1999;Hirata and Tomizuka, 2005;Ishikawa, 2008;Fujimoto, 2013;Seki and Iwasaki, 2014;Sakata et al, 2014;Ohnishi et al, 2016;. As a result, a sampled-data control system should be assumed to be the standard control system for mechatronic products.…”

In the sampled-data positioning control system of mechatronic products, it is hard to analyze the effect of mechanical resonances above the Nyquist frequency after the control systems were assembled. However, unexpected variations of mechanical characteristics often happen in actual mechatronic systems. To solve such a problem, this paper proposed two analysis methods with measurable open-loop characteristics in single-input/single-output (SISO) sampled-data positioning control systems. These methods use frequency responses of the controlled object and the digital controller for calculating the measurable open-loop characteristics without complicated calculations involving state-space representations of a controlled object, or integrations of matrix exponentials. The proposed methods indicate that we can analyze the performance of the sampled-data control system beyond the Nyquist frequency by using these measurable open-loop characteristics. To show the validity of the proposed methods, this study conducted simulation analyses on the sampled-data positioning control system of a magnetic headpositioning control system in a hard disk drive. These results show that proposed open-loop characteristics are good approximated solutions in order to analyze the control system performance of the sampled-data positioning control system beyond the Nyquist frequency.

Recent years have been characterized by marked progress in industrial instrumentation and mechatronics control technology. This year commemorates the fifth publication year of the IEEJ Journal of Industry Applications (emIEEJ J. IA). Additionally, the Mechatronics Control (MEC) technical committee was formed 3 years ago following a separation from the Industrial Instruments and Control (IIC) technical committee in order to further enhance their respective social contributions. The increased activity of both committees also contributed to the progress of the Journal. This paper discusses the recent advances and outlook in the technical field of industrial instrumentation and mechatronics control based on papers published in the IEEJ J. IA and a few other significant papers, which consider the current activities of the various committees.

“…In this paper, we clarify that the characteristic of relative positioning system constructed with flexible arm is similar to that of two-mass system. Therefore, we propose a new control system that combines the proposed observer and the self resonance cancellation (SRC) technique (Sakata, et al, 2014) in order to improve control performance of relative positioning system. The results of numerical simulation and experiments show that the proposed control system improves the relative positioning performance.…”

Precise positioning technologies are widely used in industrial machines such as device manufacturing equipment. Many studies have been done on feedback control systems for precise positioning stages that improve accuracy by using sensor signal feedback. However, the sensor output does not always directly indicate the performance of the industrial machines because the final requirement of a stage system is generally to adjust a movable stage to a target structure. Therefore, the relative displacement between the stage and the target structure must be controlled. However, the stage and other structures must be considered as elastic elements, especially for precise positioning devices. Thus, this study aims to achieve precise positioning in relative displacement between flexible structures. The authors previously proposed a relative displacement observer that estimated the relative displacement between the stage and the target structure by using only the stage displacement. In this paper, we propose additional control system for relative displacement by using self resonance cancellation technique. The positioning performance of the proposed system is evaluated in numerical simulation and experimental stage system. Results of numerical simulation and experiments show that the proposed control system improves the relative positioning performance.
