The Control of the Pneumatic Actuator Using Dahlin Algorithm

Abstract

Abstract-These In this paper, the control of the pneumatic actuator using Dahlin algorithm is proposed. Dahlin algorithm has problem which cause a steady-state error by an input-side disturbance for an integrator plant with time delay. In addition, it has problem which not ensure follow-up to a response model by parameter error of controller. To solve these problems, we introduce discrete-time IMC and iterative least squares technique. Our proposed method can remove a steady-state error caused by an input-side disturbance for an integrator plant with time delay by introducing discrete-time IMC and ensure follow-up to a response model by introducing iterative least squares technique. In the simulation, it is shown that the proposed method has a superior performance for an integrator plant with time delay. Furthermore, by applying the proposed method to a pneumatic actuator, the effectiveness of the method is examined and confirmed.Index Terms-Dahlin algorithm, discrete internal model control, auto-tuning.

Dahlin Deadbeat Internal Model Control for Discrete MIMO Systems

“…(17) (18) Two scenarios are presented. In the first one, the nominal case without any disturbances is considered, The robustness towards external disturbances of the proposed approach is presented in this scenario.…”

“…While the Dahlin controller is known for its effectiveness, it faces challenges such as steady state errors and diminished robustness due to inaccuracies in model parameters or constraints on the control as discussed in [18]. To address these issues, Dahlin algorithm was combined to robust control methods or adaptive control algorithms [18].…”

To address these issues, Dahlin algorithm was combined to robust control methods or adaptive control algorithms [18]. The Dahlin Deadbeat algorithm can be combined to discrete internal model known for its nominal performance and robustness, while considering the model structure of the process [19,20].…”
