Observation and Identification of Mechanical Systems via Second Order Sliding Modes
A second-order sliding-mode observer based on the modified super-twisting algorithm providing finite time observation is applied for system identification. The value of the equivalent output injection is used to identify perturbations directly. Continuous time versions of least square and forgetting factor methods are proposed to identify unknown time-invariant and time-variant parameters respectively
