This paper studies a heat diffusion system, that is described through the fractional operator s0.5, under the control of a fractional nonlinear algorithm. The tuning of the algorithm follows the optimization of performance control indices. The results demonstrate the good performance of the proposed controller.engFractional calculusHeat diffusion systemsNonlinear controljournal article10.1016/j.camwa.2009.08.010
