The paper proposes a new global stability analysis method dedicated to fuzzy control systems containing Mamdani fuzzy controllers with dynamics to control SISO linear / linearized plants. The method is expressed in terms of relatively simple steps based on the generalization of the describing function method to the MIMO case and on the application of the least squares method to approximate the ...

This paper presents singleand dual-loop fuzzy control schemes to precisely control the piezo-driven nanopositioner in the xand y-axis directions. Various issues are associated with this control problem, such as low stability margin due to the sharp resonant peak, nonlinear dynamics, parameter uncertainty, etc. As such, damping controllers are often utilised to damp the mechanical resonance of t...

We report on preliminary results in developing a new method for the synthesis of fuzzy-logic controllers for amplitude-sensitive nonlinear plants based on sinusoidal-input describing-function (sidf) methods. This technique exploits the fact that two traditional classes of fuzzy-logic controllers are, in functional terms, of the proportional-plus-derivative (pd) and proportional-plus-integral (p...
