SIGNAL-PROCESSING-BASED PERFORMANCE-MEASURES FOR DIFFERENTIAL LINEAR REPETITIVE PROCESSES

Repetitive or multipass processes are a class of systems characterized by a series of sweeps through a set of dynamics defined over a fixed finite duration. The output of each sweep or pass acts as an explicit forcing function on and hence contributes to the next pass profile. Th is in turn leads to the unique control problem that the output sequenc e can contain oscillations which increase in amplitude from pass to pa ss. In this paper signal-processing techniques are employed to develop unique computable performance measures of direct use in controller de sign and related studies.
