      Capítol de llibre
      Accés obert
      In this chapter, the problem of fault -tolerant control of a service robot is addressed. The proposed approach is based on using a fault estimation scheme based on a robust unknown -input observer (RUI0) that allows one ...
    • Passivation blocks for fault tolerant control of nonlinear systems 

      Bessa, Iury; Puig Cayuela, Vicenç; Martínez Palhares, Reinaldo (2021-03-01)
      Article
      Accés obert
      This paper describes a novel passivity/dissipativity based approach for fault tolerant control (FTC) of nonlinear systems by means of fault hiding, i.e., by inserting reconfiguration blocks (RBs) between the plant and ...
    • Sliding mode control of a differential-drive mobile robot following a path 

      Dòria Cerezo, Arnau; Biel Solé, Domingo; Olm Miras, Josep Maria; Repecho del Corral, Víctor (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Text en actes de congrés
      Accés obert
      This paper presents a control algorithm for a differential-drive robot following a path. The main contributions are: a new control formulation that does not require the robot global position, and a nonlinear controller ...
