Suppression of unknown periodic disturbances with time-varying characteristics has many industrial applications. The purpose of this paper is to propose a robust adaptive control scheme to suppress noise-corrupted disturbances with unknown and possibly time-varying characteristics in multi-input multi-output LTI systems. First, by considering the ideal (non-adaptive) case when complete information...
This paper proposes a strategy referred to as stability overlay (SO) for linear and nonlinear time-varying plants, that provides input/output stability guarantees for a wide set of adaptive control schemes. We use this methodology to endow multiple-model adaptive control (MMAC) architectures with robust stability properties when the plant to be controlled is uncertain and time-varying. We emphasize...
Time-delay and input disturbance frequently occur in control systems, which decrease the pre-defined performance of the closed-loop system. This paper presents an output feedback controller that compensates the performance degradation owing to time-delay and input disturbance. Simple adaptive control (SAC) and a new disturbance observer (DOB) approaches have been combined to achieve the control purpose...
