These theorems are then applied to the model reference adaptive control system with unmodelled dynamics and output disturbance to analyse the mechanism of slow-drift instability. © 1987 Taylor & Francis Group, LLC.CONTROL SYSTEMS, NONLINEAR - Analysis; MATHEMATICAL TECHNIQUES; AVERAGING ANALYSIS; MODEL REFERENCE; OUTPUT DISTURBANCE; SLOW-DRIFT INSTABILITY; UNMODELLED DYNAMICS; CONTROL SYSTEMS, ADAPTIVESlow-drift instability in model reference adaptive systems —an averaging analysisjournal article10.1080/002071787089337482-s2.0-0023288619
