This paper introduces a study for the small wind energy conversion system (WECS), which aims to select the optimum design parameters to achieve high performance system. The main features of the studied system are high efficiency, operation at maximum power point tracking (MPPT) and long battery lifetime. The Permanent Magnet Synchronous Generator (PMSG) operates at variable wind speed and it is connected...
The paper proposes an adaptive sliding observer to accurately estimate the rotor position for a direct-drive permanent magnet synchronous generator (PMSG). Without any position sensor, the generator torque and flux responses retain high performance both in the steady state and during transients. The problem on the shaft encoder installation difficulty, reliability and disturbance in encoder cable...
