Active disturbance rejection controller based on particle swarm optimization for hydraulic automatic position control system

In view of Hydraulic Automatic Position Control (HAPC) with uncertainty and nonlinearity, the model of HAPC system is established. Then, a controller independent on the model is designed. And particle swarm optimization (PSO) is presented for parameters optimization of the ADRC controller. Finally, ADRC optimized by PSO is selected as the controller for HAPC system and the simulation results show that it has better performance in tracking, anti-interference and robustness compared with other three algorithms.
