The trajectories of the proposed control algorithm are demonstrated on the phase portrait of the sliding variable in Fig 5, where S1 - S1 and S2 - S2 converge to zero.
Conclusion
In this study chattering-free robust second order sliding mode controller with PIDDα sliding surface for nonlinear systems is investigated. The main virtue of this study relies on fractional PIDDα sliding surface which provides more flexibility in the controller design. The other objective is to find an effective chattering-free robust method for nonlinear dynamic systems, by applying appropriate control action (12). Adaptation algorithm is derived based on second order sliding mode control, to estimate switching controller parameters without any knowledge about model uncertainty bound.
