Abstract :
An adaptive fuzzy total-sliding-mode controller (AFTSMC) with a total switching
surface is proposed to control the position of an electrical servodrive. The proposed controller
comprises a special fuzzy total-sliding-mode controller (FTSMC) and an adaptive tuner. The
FTSMC acts as the main tracking controller, which is designed via a fuzzy system to mimic the
merits of a total-sliding-mode controller (TSMC). In addition, a translation width is embedded into
fuzzy rules to reduce the chattering phenomena. The adaptive tuner, which is derived in the sense of
Lyapunov stability theorem, is utilised to adjust the translation width on-line for further assuring
robust and optimal performance. In the AFTSMC, the fuzzy-control-rules base is compact and
only one parameter needs to be adjusted. An electrical servodrive with the proposed positioncontrol
system possesses the advantages of a simple control framework, reduced chattering, stable
performance and robustness to uncertainties. The effectiveness is demonstrated by simulated and
experimental results, and its advantages are indicated in comparison with conventional TSMC and
adaptive TSMC for a field-oriented control induction-motor (IM) drive.
