In this work, we deal with a micro electromechanical system (MEMS), represented by a micro-accelerometer. Through numerical simulations, it was found that for certain parameters, the system has a chaotic behavior. The chaotic behaviors in a fractional order are also studied numerically, by historical time and phase portraits, and the results are validated by the existence of positive maximal Lyapunov...
In this paper, based on the theory of sliding mode control and fuzzy logic control, a new fuzzy sliding mode controller with a fixed-order compensator (FSMC&C) has been presented for application to seismically excited building structures. The major advantages of this method over the conventional sliding mode control are as follows: (i) it make trade-offs between control efforts and specific response...
This paper presents the design of a fuzzy sliding mode loss-minimization control for the speed of a permanent magnet synchronous generator (PMSG) and proportional-integral (PI) for the turbine pitch angle control. The PMSG speed uses maximum power point tracking below the rated speed, which corresponds to low and high wind speed, and the maximum energy can be captured from the wind. A sliding mode...
For flight motion simulator servo system, this paper presents a kind of fuzzy sliding mode controller based on optimal fuzzy reasoning according to sliding mode control and fuzzy control theory. Sliding mode controller (SMC) is a special nonlinear control strategy, which has strong robustness against parameter variations and external disturbances, but the chattering produced by sliding mode control...
