This paper presents the nano-positioning control of a piezoelectric platform. A Bouc-Wen model is established to describe the nonlinear hysteretic effect of piezoelectric systems. Three kinds of compensators, traditional PI controller, PI-like fuzzy logic controller (FLC) and adaptive PI-FLC controller, are designed for the piezoelectric systems. The adaptive PI controller is tuned on-line by m...

The Bouc Wen magnetorheological damper model has eight unknown parameters, and the mathematical expression of includes evolution quantity, absolute value term, exponential term differential equation, which complicates parameter identification. Researchers in related fields have made numerous attempts to solve problem that model's identification method is complex difficult implement. A combining...

Abstract. This paper presents reviews of several models and numerical simulation models of non-linear and hysteresis behaviors of magneto-rheological liquid dampers in MATLAB®/Simulink® in the example of quarter-car model of vehicle suspension simulation, such as, Bingham, Dahl, LuGre and Bouc-Wen models. In addition, it demonstrates numerical simulation models built in MATLAB®/Simulink® and di...

This paper presents a study on improving the estimation accuracy and convergence rate of hysteresis modeling MFC actuators using mutation enhanced differential evolution (MEDE) algorithm, modified version algorithm. The proposed MEDE algorithm uses three strategies, i.e., best, rand, pbest. To model secondary path smart flexible beam with actuators, Hammerstein that combines an asymmetric Bouc-...

This paper established the equivalent linear motion equation of TRMD. To further investigate potential application TRMD in nonlinear vibration, Bouc-wen model structure with is provided, vibration control efficacy and hysteretic characteristics main under harmonic excitation are analyzed. The results show that suppresses displacement while loop energy dissipation capacity itself reduced. For so...
