摘要: This paper concerns with the problems of tracking control and disturbance rejection for two types non-minimum phase (NMP) systems associated right half plane (RHP) zeroes time delay, respectively. As achievable closed-loop bandwidth such is usually very limited, obtaining good becomes great challenges in design. For rejection, this mainly focuses on method active (ADRC), where modifications tuning, ESO ADRC structure are made to make solutions more effective NMP systems; fast tracking, a unique feedforward design combined solution overcome limitation. The proposed methods validated simulation satisfactory performance give practitioners set tools deal systems.
