Online Tuning of Two Degrees of Freedom Fractional Order Control Loops
This paper presents online tuning of Two Degrees ofFreedom control loops with fractional order proportionalintegral-derivative controller. Since, simultaneous systemobjectives can be achieved by these types of control loops it canbe used for challenging control problems. Thus, five variouscontrol loops are reconfigured with fractional order integral andderivative expressions for real time controller tuning problem.Seven parameters of the modified control loops are optimized viastochastic multi parameter divergence optimization algorithm.The optimization algorithm employs good performance for onlinetuning. The performance of the five various structures arecompared using simulation model and real time experimentalstudy on a prototype flight control simulator.
