“…C p is the sixth order polynomial of the tip-speed ratio. C p curve is modeled based on the sixth order polynomial expression [16]. Curve fitting is a good approximation for wide wind speed values between 2 m/s and 15 m/s.…”

“…Because no initial position problem and operating at flux-weakening region exist, sensorless control is a significant cost reductive solution for the control of PMSG drives. Determining the wind speed and rotor position can be accomplished with the methods which are Direct Torque Control (DTC), Model Reference Adaptive System (MRAS), and Sliding Mode Observer (SMO) depending on back-EMF prediction [8,[14][15][16][17][18]. Because these methods are often affected by parameter variation and cause loss of stability at low speeds, they have severe disadvantages in sensorless PMSG control [19][20][21].…”

A simple and efficient position sensorless control method based on feedforward voltage estimation for PMSG improved with multi-parameter estimation using MRAS is proposed in this paper. The dynamically enhanced stator feedforward dq-axes voltages that are derived from steady-state PMSG model are modified for the sensorless drive. In direct-drive wind turbine systems, because of low back-EMF amplitude in the generator output at very low speed operation, the rotor flux linkage cannot be predicted correctly. Vector control is often used in PMSG control, because it has a simple structure and is suitable for various industrial systems. In the power equation, maximum power is obtained as a function of torque and speed. In the proposed method, a variable-speed wind turbine system with back to back converter structure is connected to common DC-link. In this paper, the proposed sensorless control scheme has been implemented with 1 kW PMSG drive controlled by a TMS320F28335 DSP for low speed at 0.1 p.u. (300 rpm) is achieved under multi-parameter variations. Keywords

“…15, this command is based initially on the calculation of the reference current based on the knowledge of the wind turbine characteristics and the calculation of the optimal power using Eqs. (23), (24), and (25) [16]. Then we use this reference current to calculate the sliding surface and the equivalent control in order to conclude a better control signal to properly reach and follow the wind system maximum power point.…”

In this paper, we present a modeling and simulation study of a hybrid energy system for isolated sites, which combines photovoltaic system with wind turbine based on permanent magnet synchronous generator (PMSG). With the aim of improving the performances and extracting the maximum energy produced by the two Photovoltaic (PV) and Wind sources, we developed a maximum power point tracking (MPPT) controller with robust algorithms based on the nonlinear sliding mode control (SMC). Thus, other conventional MPPT methods have been simulated and evaluated to compare them with the proposed algorithms in order to deduce the most efficient in terms of the maximum power reach and the system behavior during optimal power point tracking. And for a better analysis study, the simulations are carried out under variable weather conditions. The simulation results show that the proposed robust sliding mode control techniques (RSMC) are more efficient and have better performance than other MPPT algorithms.
