ABSTRACT
The stiction characteristic of pneumatic control valve usually leads to the appearance of oscillation phenomena and deteriorates the closed-loop system performance. Thus, modeling the valve stiction is necessary. This study proposes a new system model based on the two-parameter stiction model and the Hammerstein model and exploits the Particle Swarm Optimization (PSO) to estimate the two parameters of the stiction model. At last, simulation and experimental examples verify the effectiveness of the proposed method.
