    A new adaptive nonlinear state predictor (ANSP) is presented for a class of unknown nonlinear systems with input time-delay. A dynamical identification with neu- ral network (NN) is constructed to obtain NN weights and ...
  • Disturbance Observer based Repetitive Controller for Time-Delay Systems 

    Na, Jing; Costa Castelló, Ramon; Griñó Cubero, Robert; Xuemei, Ren (2009-09-22)
    Conference report
    Open Access
    This paper presents a discrete control design for time-delay systems subjected to the periodical command signal or exogenous disturbances. Unlike other deadtime compensators (DTC), we take profit of the system components ...
  • Repetitive control for systems with time-delays and application to robotic servo motor 

    Na, Jing; Ren, Xuemei; Costa Castelló, Ramon; Griñó Cubero, Robert; Guo, Y. (2012)
    Conference lecture
    Restricted access - publisher's policy
    In many industrial robotic applications there is a need to track periodic reference signals and/or reject periodic disturbances. This paper presents a novel repetitive control design for systems with constant time-delays ...
