Use of fuzzy logic in adaptive "morphological" controllers
In this paper, fuzzy logic-based adaptive morphological control (MC) is proposed. MC generalizes the idea of variable structure control (VSC). In the conventional approach to VSC, the control surface does not change the shape during a step response. A morphological type of VSC changes the shape of the control surface during each step response to increase system performance. This MC's "varying structure" property provides an extra degree of flexibility to combine different control goals such as robustness and minimum time control. A TSK type FLC with sliding mode controller (SMC) functions as the rule output function is developed, which is used as a controller in MC approach. Simulation results with a DC motor model are presented.<<ETX>>
