摘要
An alternative of fuzzy-based sliding mode control is reported in this paper so as to reduce chattering for a two degrees-of-freedom (2-DOF) platform driven by electro-pneumatic actuators. According to surface function values, a Mamdani fuzzy inference system is introduced to change the control action over the actuators and the slope of sliding surface to minimize chattering. In addition, although pneumatic actuators present high nonlinearities, experimental results are reported with attenuation of chattering and convergence toward the reference, in spite of the existence trade off between accuracy and system behavior for sliding mode controller.
