Abstract :
Adaptive sliding mode control (ASMC) based on wavelet network observers (WNO) for nonlinear systems is presented. Despite no state measurement, the design employs wavelet networks (WN) which parameters are tuned online by the constructed proper adaptive laws to observe the inner state dynamics and compose the appropriate SMC control law. By combining the WNO with the SMC design, robustness and adaptiveness characters of the closed-loop systems are achieved. The results of simulation on an inverted pendulum (IP) experiment system are given to verify its effectiveness and performance.
