“…To solve this problem, we associate another control term γ 1 that will be the output of a PI controller, the idea is inspired from [8] were the author combine a PID control action with a nonlinear control law. Thus the final expression controlling the current output will be the sum of a decoupling action and a PI control action.…”

Abstract-A new control strategy is presented in this paper, based on previous works limited to the control of the capacitor voltages considered as the outputs of a three cell converter. An additional control input is proposed to this latter in order to obtain the desired current output. The experimentations performed on a multicellular converter are presented and the discussed results showing the efficiency of the contribution.

“…Examples of the techniques used in MFC are fuzzy logic sets and neural networks, to mention few. Recently, another variant of MFC based on the principle of ultralocal model is investigated, which has been implemented in various applications [21]- [22]. It is noteworthy to mention that being model-free does not necessarily imply the absence of any dynamic model, which will be shown shortly.…”

Enhancing the performance of heaving wave energy converters using model-free control approach

a b s t r a c tThis paper investigates the application of model free control (MFC) strategy to optimally control the oscillation of single body heaving waves energy converter (WEC). The aim of the proposed controller is to maximize the electrical energy output of the device. The MFC is an off-line fixed structure control approach that combines between simplicity and insensitivity to system uncertainties and/or operational conditions. The proposed controller is based on a classical linear compensator, which is designed and tuned using only the well-known dynamics of the WEC. Therefore, any extra unknown or partially known dynamics are taken care of using the ultra-local model (ULM). Simulation results show that the MFC performance is superior to that of the base linear compensator, in terms of reference tracking capability and robustness towards uncertainties. Also other well-established control strategies are used to further validate the proposed controller.

“…Also in [12], a discrete-time sliding mode approach is introduced for variable speed wind turbine system. In order to improve the efficiency of MPP tracking, a novel controller relying on an intelligent proportional-integralderivative (iPID) control is proposed in [13], it has been proved to produce efficient control for a variety of systems such as a quadrotor vehicle [14], DC/DC converters, and motors [15]. This approach uses an observer which is based on algebraic techniques to estimate the unknown dynamics [16].…”
