A Novel Sensorless MPPT Controller for a High-Efficiency Microscale Wind Power Generation System

Grid-integrated permanent magnet synchronous generator based wind energy conversion systems: A technology review

“…ORB control ensures MPPT using a precalculated look-up table which is structured with the aid of knowledge of optimum relationships among various system parameters [10,27,28,43,63,82,120,142,154,157,164]; for instance, the power versus shaft speed [27,90,165], the power versus torque [157,166,167], the power versus rectified dc-link voltage [63] and the dc-link voltage and dc-side current [142]. The ORB control is simple to implement, has good dynamic response, requires no wind speed sensor, can produce smoother output power when compared with the other strategies and is widely used in commercial WECSs [23,154,168].…”

A novel fuzzy integral sliding mode current control strategy for maximizing wind power extraction and eliminating voltage harmonics

“…The fuzzy logic generator and current controller can be reasonably designed based on Eqs. (8)e (11) and Eqs. (12)e(30), respectively.…”

“…The hill-climb searching control method can also be employed to dynamically search for the maximum power points and hence to drive the turbine operating points towards these optimum points without requiring the prior knowledge of wind turbine characteristics and wind speed [10,11]. Although relatively flexible and simple, this control method suffers from the problems of highfrequency oscillations and large steady-state errors.…”

Adaptive Control Topology based Optimization of Wind Power Dispatch

“…The particular MPPT methods usually are primarily is dependent upon wind flow velocity calculations/estimations, output power measurement/calculation and characteristic power curve [13]. They're used in control systems like tip speed ratio (TSR), the optimal torque (OT), the power mapping and the perturbation & observation (P&O)/hill climbing searching (HCS) [14].…”
