USING REPETITIVE CONTROL TO ELIMINATE PERIODIC DISTURBANCES IN DAMPER TEST RIGS

Using Repetitive Control to Eliminate Periodic Disturbances in Damper Test Rigs

Repetitive Control is a relatively new technique for controlling systems that contain periodic reference signals or periodic disturbances. The fundamental idea behind the method is to use the internal model of the periodic signal to guarantee asymptotic reference tracking or disturbance rejection. In this paper two recent Repetitive Control algorithms are applied to a simulation model of a damp...

Filtered-X LMS vs repetitive control for active structural acoustic control of periodic disturbances

This paper presents a comparison of repetitive control and narrowband filtered-X LMS feedforward control, both applicable in the field of active structural acoustic control (ASAC) and active noise control (ANC) of periodic disturbances. This can be useful for example in rotating machinery, where the disturbance is often determined by the rotational speed. A frequency domain relation between the...

Rejection of Periodic Disturbances Based on Adaptive Repetitive Model Predictive Control

The paper presents an adaptive strategy to reject periodic disturbances with unknown period based on a combination of model predictive control and repetitive control. A novel period estimator is presented. For the integer period case, the estimator is designed based on integer programming. For the non-integer period case, it is designed based on a two-step optimization, namely integer programmi...

Quasi-sliding mode based repetitive control for nonlinear continuous-time systems with rejection of periodic disturbances

A Quasi-Sliding Mode (QSM) based tracking control method for tackling Multiple-Input Multiple-Output (MIMO) nonlinear continuous-time systems with un-matching system uncertainties and exogenous disturbances is proposed. The presented Repetitive Control (RC) scheme ensures robust system stability when the system is subject to non-periodic uncertainties and exogenous disturbances. The complete re...
