Improved WSA for adaptive FLC in non-symmetrical hydraulic servo-system

Fuzzy logic controller (FLC) performs well in nonlinearity system, while the tuning of FLC is still a challenge. In this paper, FLC is applied to non-symmetrical hydraulic system. To obtain a satisfactory control performance, WSA-IC is used to build adaptive FLC. We test the FLC obtained by WSA-IC using a benchmark control plants and a hydraulic servo-system. Simulations results show that WSA-IC based FLC performs better than GA, DE, and some other heuristic algorithms.
