Comparison of integer and fractional order controller of battery discharge based DC-DC converter

This paper deals with an efficient method to ensure an optimal power flow in water pumping system based on renewable energy. In this context, this study aims to find a global supervisory strategy with an optimal adjustment of the DC-bus voltage enhancement. In the proposed study, a firefly algorithm is employed as the key optimizer of the supervisory power exchange in order to improve the different power flows exchanged among the system devices. The water pumping system (WPS) is made up of a wind turbine (WT) required as the principal renewable energy source associated to a battery energy storage system (BSS) to ensure the power supply continuity of a moto-pump system. The models of WPS units and the control strategy are developed using MATLAB software. The simulation results are provided to show the considerable improvement for the system as regards both of voltage stability and the feasibility of power management strategy.

“…The most practical situation is the second one where it is required to design a fractional‐order controller to improve the performance of an integer‐order system. An important example of this can be found in power electronic circuit applications and particularly switching DC/DC converters 3‐7,20,23‐47 . As can be noticed from most of these contributions, the designed fractional‐order controllers require digital signal processing techniques, which adds an extra overhead on present implementations of switching DC/DC converters in commercial products.…”

Switching DC/DC converters are closed loop systems requiring controllers to stabilize and optimize their performance. A practical method for designing these controllers through pole/zero placement adjustment is the K-factor method. This method can easily be implemented using RC op-amp circuits given a target crossover frequency and phase margin. Here, we extend this method to the fractional-order domain and present detailed analytical formulae to calculate all component values in two types of op-amp-based compensators. Mathematical analysis, circuit simulation, and experimental results all correlate very well.
