This paper proposes an adaptive full-order Sliding Mode Observer (SMO) for the rotor speed and position estimation in the Permanent Magnet Synchronous Generator (PMSG). A full-order terminal SMO is designed to make the estimated stator current track the actual stator current, and eliminate the chattering. Furthermore, A back Electro Motive Force (EMF) observer adopts adaptive control to estimate the...
The paper firstly establishes a port-controlled Hamiltonian dissipation (PCHD) based model of a direct-drive permanent magnet synchronous generator (D-PMSG). A new double loop control of the D-PMSG is proposed with the outer speed loop controlled by a non-singular higher-order terminal sliding mode (NHTSM) controller to undertake maximum wind power point tracking (MPPT). In the inner current control...
