The main contribution of this paper is the investigation of different model reference adaptation schemes for improving the performance of fuzzy logic control. Adaptive fuzzy control strategies are based on: i) fuzzy control with fuzzy internal model; ii) fuzzy control with fuzzy compensation; and iii) proportional and integral control with fuzzy adaptation. Numerical and experimental results are shown in order to assess the performance of each adaptive fuzzy control algorithm in nonlinear processes.
