Brushless DC Motors Control Based on Smith Predictor Modified by Fuzzy-PI Controller
FSKD '08: Proceedings of the 2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery - Volume 03This paper discusses the time lag in brushless DC motor system, which leads to increase system dynamic error, decrease stability margin and affect the system stability. Based on the Smith compensation control theory, the predictor of time lag is ...
Enhanced modified Smith predictor for second-order non-minimum phase unstable processes
