As a particular and complex underactuated mechanical system, underactuated truss-like robotic finger (UTRF) is studied by establishing its dynamic model. The control problems include high nonlinearity, model inaccuracy and uncertainties. Type-2 fuzzy logic control method is supposed to be a proper way to solve these problems, because fuzzy logic control itself does not depend on an accurate model of the controlled object, and type-2 fuzzy logic control is able to handle uncertainties. The basic principle of type-2 fuzzy logic control is then analyzed. Moreover, an interval type-2 fuzzy logic controller is designed for UTRF to accomplish the goal of stabilization in its equilibrium point. Simulation result shows that the designed interval type-2 fuzzy logic controller is correct and effective. 收起
