In this study, a fractional order PID (FOPID) controller is designed and
used to control a DC-DC non-inverting buck-boost converter (NIBBC) for a
wave/ultra-capacitor (UC) energy system. Because of the energy discontinuities
encountered in wave energy conversion systems (WECS), an UC is integrated to
the WECS. In order to obtain the best controller performance, particle swarm
optimization (PSO) is employed to find the optimum controller parameters.
Integral of time weighted absolute error (ITAE) criteria is used as an
objective function. Also, an optimized PID controller is designed to test the
performance of the FOPID controller. The whole system is developed in
Matlab/Simulink/SimPower environment. The simulation results show that the
FOPID controller provides lower value performance indices than the PID
controller in terms of reducing the output voltage sags and swells.
