“…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
