Актуальність. Налаштування ефективних параметрів регулятора як при моделюванні САР, так і на реальному об’єкті, залишається актуальною задачею побудові систем регулювання, зважаючи суперечливі вимоги у забезпечені високої динамічної точності стабілізації регульованої змінної стійкості системи. Ця задача потребує крім знань теорії автоматичного керування, також навиків застосування сучасних паке...

Numerous tools automating various aspects of software engineering have been developed, and many of the tools are highly configurable through parameters. Understanding the parameters of advanced tools often requires deep understanding of complex algorithms. Unfortunately, sub-optimal parameter settings limit the performance of tools and hinder industrial adaptation, but still few studies address...

The objective of this paper is to understand the critical parameters that need to be addressed while designing a guitar tuner. The focus of the design lies in developing a suitable algorithm to accurately detect the fundamental frequency of a plucked guitar string from its frequency spectrum. A user-friendly graphical interface is developed using Matlab to allow any user to easily tune his guit...

We have locked a whispering-gallery resonance of a fused-silica microsphere to a frequency-scanning laser. The resonance frequency is modulated by axial compression of the microsphere, and phase-sensitive detection of the fiber-coupled optical throughput is used for locking. Using a laser wavelength of either 1570 nm or 830 nm, we demonstrate a locked tracking range exceeding 30 GHz for a micro...

Several neural-net based PID controllers have been proposed for nonlinear process systems. However, they have been not so widely used in process industries due to the considerably computational cost. This paper presents a new intelligent PID tuning scheme, whose PID tuner is constructed by the fusional structure of a cerebellar model articulation controller and a neural network. This PID tuner ...

New storage ring cavity temperature system was successfully operated for the Pohang Light Source (PLS) and increased the stable maximum beam current up to 200 mA. The storage ring cavity for PLS has the plunger-type tuner which is controlled by the phase feedback loop to always tune the resonant frequency. Optimum temperature windows for the PLS cavities were obtained by intensive but tiresome ...

The passive dynamic walker (PDW) has an interesting characteristic that it realizes cyclic locomotion without planning joint trajectories. On the other hand, the walking behavior cannot be controlled because it is dominated by the fixed body dynamics. Observing the human cyclic locomotion that is activated by elastic muscles, we adopt a compliant hip joint on PDW, and we propose the ”phasic dyn...
