چکیده مقاله
This paper examines the feasibility of applying fuzzy sliding mode control FSMC strategies to reduce the dynamic responses of a seismically excited structure FSMC is a combination of sliding mode control SMC and fuzzy control which gather advantages of sliding mode, fuzzy inference mechanism to enhance robustness and sliding performance of the system First, the control rules are constructed according to the concept of SMC, and then fuzzy sets, whose membership functions are symmetrically covered in the state space, are defined Switching type control law of the conventional SMC and uncertainty part of the equivalent control is approximated by fuzzy controller to attenuate the chatteringphenomenon and harmful effects caused by uncertainties Numerical results indicate that applying this FSMC to control a seismically excited structure can reduce the response quantities to a satisfactory level
