Particle Swarm Optimization, Tuning, PID control, Positional Servomechanism


The paper proposes a simple and effective tuning technique that yields optimal proportional-integral derivative (PID) parameters for a positioning servomechanism. The proposed tuning technique utilizes the particle swarm optimization (PSO) algorithm as an optimization strategy to determine optimal tuning parameters. Comparisons are made between the proposed method and other tuning methods. The usefulness of the proposed method is demonstrated through an experimental study of a position servomechanism under setpoint changes and load disturbances.
