Sanchez Torres, “A fixed-time second order sliding mode observer for a class of nonlinear systems”, in 13th International Workshop on Variable Structure Systems (VSS); Nantes, France, 2014.2158-3978http://hdl.handle.net/11117/3283This paper presents a second order fixed time sliding mode observer based on an extension of the super-twisting algorithm. This observer can be applied to a class of nonlinear system with a block-wise representation. The block structure provides a straightforward form to the application of the proposed second order sliding mode algorithm, yielding to finite-time convergence with a settling time independent to the system initial conditions. Finally, as numerical simulation example, the case of a linear induction motor is studied, exposing the efficiency and feasibility of the proposal.engRobust ControlFixed Time StabilityState Observersinfo:eu-repo/semantics/conferencePaper
