Item type:Publication, Development of Remote Laboratory for Feedback Control System Class(2021-01-01); ; This research presents a low cost web-based remote laboratory system for a feedback control system class. The system is created by an inexpensive single-board computer (Raspberry Pi 3B+) as laboratory server, an edge of extinct Lego Mindstorms set as a controlled plant, and an IP camera system. The laboratory server based on Ubuntu, which is a free and open-source software and the web application is written with JavaScript based on a MEAN stack platform. The proposed laboratory is used for verifying a design project of the angle control system using Proportional-Integral-Derivative (PID) control. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Hysteresis Modeling of Lithium-Silicon Half Cells Using Prandtl-Ishlinskii Model(2020-10-09); Plett, Gregory L.State-of-charge (SOC)-estimation accuracy is critical to battery management in electric-vehicle (EV) applications. SOC-estimation error can arise from unmodeled nonlinear battery hysteresis; so to enhance performance, it is necessary to model hysteresis voltage. This paper presents results from applying three kinds of Prandtl-Ishlinskii (PI) model to a Li//Si half cell: classical PI (CPI), generalized PI (GPI), and modified generalized PI (mGPI). The performance comparison among these models and also comparisons to the Preisach and Krasnosel'skii-Pokrovskii (KP) models are made. It is found that the mGPI provides best performance among all models having the same level of calculation.
