In this study, a singlesensor-basedmaximumpowerpointtracking (MPPT) algorithm is presented for permanent magnet synchronous generator-based wind energy conversion system (WECS). The MPPT method used in this study uses only the wind speed sensor to generate the reference point required for the maximumpower. A discrete-time controller is proposed to bring the system to the reference point determined by the MPPT algorithm. The designed MPPT controller consisting of a new discrete-time reaching-law approach and a discrete-time integral sliding mode control (SMC). The designed discrete-time SMC-based controller is implemented by using an Acorn RISC Machine (ARM)-based LM4F120 microcontroller, and its performance is examined on a WECS emulator prepared in the laboratory. The results got from the real-time studies prove that the proposed controller has the satisfactory performance to bring the system to the MPP. The performance of the proposed controller is also compared with the conventional sliding mode controller and perturb and observe method. The obtained results proved that the proposed controller has a better performance than the other controllers in terms of the settling time and output voltage's ripple.
