system identification and optimization of fuzzy relation matrix models based on semi-tensor product
abstract
generally, in real-world engineering disciplines a dynamical system is nonlinear, having multi-input and multi-output (mimo) variables, and high level parameter uncertainties. although there are many approaches proposed in the literature for system modeling and optimization, it remains a challenging topic to derive the precise mathematical models to characterize complex, dynamic and globally described systems. if training data in a real-world system are available, artificial neural network theories can be applied for system parameter recognition and optimization. the objective of this work is to develop a new fuzzy formulation based on the semi-tensor product (stp) method to construct fuzzy logic models for mimo systems in a matrix representation. it involves the following processing operations: fuzzy modeling, structure and parameters identification, system optimization, and adaptive control of closed-loop fuzzy systems based on the fuzzy relation matrix (frm) models and stp algorithms. the related contributions are summarized below.
