An Adaptive Controller for Multimodal Systems Based on Fuzzy Reference Model Generator

Abstract — This paper presents a novel adaptive controller for multimodal systems based on Fuzzy Reference Model Generator (FRMG). The proposed scheme consists of a fuzzy logic switching method working along with a Model Reference Adaptive Control (MRAC) framework. The fuzzy switching scheme produce a ‘soft’ way of generating the reference model, combining a group of weighted reference models at each plant operating point. Unlike static multiple model algorithms, this scheme provides an interactive multiple model environment with soft switching. Simulation results conducted on two practical examples of multimodal systems show that the scheme is computationally feasible, efficient and fault tolerant in nature
