Multi-Restricted Area Avoidance Scenario Using Hybrid Dynamical Model and Its Predictive Controller

by Sutrisno, Widowati, R. Heru Tjahjana, Sunarsih and Kartono

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 4, Page # 147–151, 2019; DOI: 10.25046/aj040418

Abstract:

This article is addressed to show the results of hybrid dynamical modeling in the form of PWA (piecewise-affine) and equivalent MLD (mixed-logical dynamical) model for multi-restricted areas avoidance of an autonomous system. It is a problem of determining the optimal moving trajectory from plant’s initial position to some desired position while avoiding some restricted areas…

Real-Time Flux-weakening Control for an IPMSM Drive System Using a Predictive Controller

by Tian-Hua Liu, Shao-Kai Tseng, Yi Chen and Mao-Bin Lu

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 6, Page # 76–86, 2017; DOI: 10.25046/aj020610

Abstract:

This paper proposes extended-range high-speed control for an IPMSM drive system. A simple real-time tuning flux-weakening control algorithm is proposed and implemented to control an IPMSM drive system in a wide variable speed range, from 3 r/min up to 2700 r/min. This flux-weakening control algorithm does not require any motor parameters and only needs simple…
