PSO modelling and PID controlled of automatic fish feeder system
… feeding system by using PID controller through ARX modelling. In this study, raw data at distribution part with speed of 130 rpm, 160 rpm, 190 rpm, 220 rpm and 250 rpm were extracted and used to determine ARX equation parameters as transfer function by using PSO algorithm to optimize ARX model …

Sensorless temperature estimation and control of Peltier devices
… at a rate of 200 Hz between pulses. A low order ARX model is then used to estimate the SMA temperature. The SMA temperature can be controlled using this estimate. This method will enable the production of large arrays of TED-driven SMA tendon actuators, particularly for large DOF robotic systems.

Time-frequency investigation of heart rate variability and cardiovascular system modeling of normal and chronic obstructive pulmonary disease (COPD) subjects
… time-frequency representations are evaluated on modeled HRV test signals, actual electrocardiograms (ECG), BP and RESP signals. Each distribution: the short time Fourier transform (STFT), the smoothed pseudo Wigner-Ville (SPWVD), the ChoiWilliams (CWD), the Bom-Jordan-Cohen (BJC) and wavelet …

Application of vibration-based damage detection techniques to civil infrastructure : incorporating uncertainty quantification
… Frameworks for the application of non-model-based vibration-based damage detection techniques, incorporating uncertainties, were developed. The frameworks consisted of data collection, feature extraction, feature discrimination and damage diagnosis with a quantitative measure of …

Estimation of cardiovascular indices by analysis of the arterial blood pressure signal
… within the framework of a generalized Windkessel model, which is a widely accepted cardiovascular model. Algorithms to identify end systole were also developed and implemented in the new and existing SV, CO, and TPR estimation algorithms. The algorithms were validated by applying them to …

Development of temperature and feed rate controllers for a hybrid thermoplastic forming of surgical blades from bulk metallic glass
… along with Auto-Regressive eXogenous, ARX model to the test bed, which can maintain the steady state temperature within the range of ± 2.5 K. In terms of the thermoplastic drawing process, a cascade P-PI controller is deployed. This controller improves the consistency of the position …

Bayesovské přístupy pro adaptivní identifikaci systémů
… časově variantních normálních regresních modelů a skýtá celkem čtyři hlavní algoritmy. První dvě uvedené algoritmizace slouží pro průběžnou regularizovanou identifikaci jednoho regresního modelu. Neznámost časového vývoje tohoto modelu je u obou algoritmizací řešena technikou datově …
