Performance assessment of nonlinear control systems based on fuzzy modeling

This note concerns with performance assessment problem for nonlinear control systems. Because of the difficulty finding a suitable benchmark performance for the nonlinear control systems, this problem is still open by now. With the help of the so called Takagi-Sugeno fuzzy model, the benchmark controller and its associated benchmark performance are proposed based on linear time-variant model transformed by the nonlinear system. Final simulation result well shows the effectiveness of the proposed assessment procedure.
