Robustness of optimized FPID controller against uncertainty and disturbance by fractional nonlinear model for research nuclear reactor

In this study, a fractional order proportional integral derivative (FOPID) controller is designed to create the reference power trajectory and to conquer the uncertainties and external disturbances. A fractional nonlinear model was utilized to describe the nuclear reactor dynamic behaviour consideri...
