Discrete-Time Nonlinear Damping Backstepping Control With Observers for Rejection of Low and High Frequency Disturbances

A discrete-time backstepping control algorithm is proposed for reference tracking of sys- tems affected by both broadband disturbances at low frequencies and narrow band distur- bances at high frequencies. A discrete time DOB, which is constructed …
