Abstract
Abstract
An Intelligent Pneumatic Actuator (IPA) system is known to be highly nonlinear, subject to nonlinearities which make it difficult to control the precise position of the actuator. Thus, system modelling is crucial in creating a mathematical model that demonstrates the dynamics of a system. In this study, the pneumatic system has been modelled by an autoregressive with exogenous input (ARX) model structure, while PID and fractional orders PIλDμ (FOPID) were used as control strategies. Finally, a simulation-based comparative analysis was evaluated and addressed to decide which controller provides a better tracking performance (Steady State Error (e ss), Percentage of Overshoot (%Os), Settling Time (7¾ and Rise Time (7>)).
