Abstract

This paper presents online tuning of Two Degrees of

Freedom control loops with fractional order proportionalintegral-

derivative controller. Since, simultaneous system

objectives can be achieved by these types of control loops it can

be used for challenging control problems. Thus, five various

control loops are reconfigured with fractional order integral and

derivative expressions for real time controller tuning problem.

Seven parameters of the modified control loops are optimized via

stochastic multi parameter divergence optimization algorithm.

The optimization algorithm employs good performance for online

tuning. The performance of the five various structures are

compared using simulation model and real time experimental

study on a prototype flight control simulator.
