Control Of Servo Systems In The Presence Of Motor-Load Inertia Mismatch, Jeffrey W. Moscrop, C. Cook, P. Moll
Control Of Servo Systems In The Presence Of Motor-Load Inertia Mismatch, Jeffrey W. Moscrop, C. Cook, P. Moll
Faculty of Informatics - Papers (Archive)
There are a number of performance limiting factors that concern the designers of machine tool servo systems. One such factor is the mismatch that often exists between motor and load inertias. This paper briefly discusses the results of a previous study on the factors that interact to introduce stability problems in the presence of a high motor-load inertia mismatch. The effects of such an inertia mismatch, on servo system performance, are then discussed and analysed using closed loop frequency responses. Various methods of improving the system response using fast feedback control are presented, including traditional PI control and modern methods …

This paper presents boundary optimization techniques for the processing of arbitrary-length signals with paraunitary multirate filter banks. The boundary filters are designed to maximize the coding gain while providing an ideal DC behavior. Thus, all filters except the lowpass filter are designed to have zero mean. The proposed methods give direct solutions to the problem of finding optimal boundary filters and do not require numerical optimization.
