Optimal Tuning of Fractional Order PID Controller
The paper proposes a comparative study of the performance of the fractional order PID(FOPID) controller with the conventional controllers. The parameters of the FOPID controller is estimated using particle swarm optimization (PSO) algorithm, and the values are compared with the values obtained through conventional optimization techniques. This paper aims to find out optimal settings for a fractional PIaDb controller in order to achieve five different design specification for a closed system and also presents identification of fractional order system using PSO. By obtaining optimal settings, fractional order PID controller can enhance system control performance and robustness.
