Design of a New Adaptive Fuzzy Sliding Mode Controller with Application to Vehicle Seat MR Damper for Vibration Control

다국어 초록 (Multilingual Abstract)

This paper presents a new design of adaptive fuzzy sliding mode control based two methodologies: H infinity control technique and sliding mode control. The sliding surface of sliding mode control is analyzed into two matrices: Hurwitz constants matrix and constant matrix. These matrices are basis for establishing the proposed control and subsequently are combined with H infinity technique method. The control from the combination of H infinity and sliding mode is reinforced by a new robustness function, which relates the previous control function and exponential function. In addition, a fuzzy logic model is integrated with the proposed algorithm to keep the advantages even in uncertain environment of the dynamic system. The proposed control is evaluated by magnetorheological (MR in short) seat damper system for vibration control. In addition, two existing controls are modified and compared with the proposed control to highlight some advantages of the proposed control scheme. It is demonstrated that from vibration control results the proposed control is much better performance than the existing two controllers.
