Robustness of an adaptive pole placement algorithm in the presence of bounded disturbances and slow time variation of parameters
MetadataShow full item record
The purpose of this note is to study the robustness properties of a specific adaptive pole placement scheme in the presence of bounded disturbances and slow time variation of parameters. We show that the least squares (with block processing) algorithm used in this scheme has the remarkable property of retaining the global stability of the overall system in the presence of bounded disturbances of small magnitude and slow time variation of system parameters (within a compact set.)
