摘要: Rejection of periodic signals has been a subject great interest in control theory and engineering applications. Periodic disturbances are usually present mechatronic, hydraulic electronics systems, between others. This paper proposes resonant observer-based for signal rejection. The observer includes, an embedded way, internal model the disturbance that is based on its harmonic decomposition. resulting estimation used by law cancels term while controlling specified tracking task. proposed scheme lets designer to address problems separately. Experimental results, mechatronic test bed, show successfully rejects disturbances.
