4次同一次元状態オブザーバを利用したPMSMセンサレスベクトル制御への一般化積分形PLL法の適用可能性

抄録

This paper newly shows applicability of the generalized integral type PLL method to sensorless vector controls of permanent magnet synchronous motors using full-order state observer, which have identified rotor speed as a system parameter separately from rotor phase treated as a system state by adaptive identification algorithm so far. The PLL method can exploit the integral-derivative relation between phase and speed, consequently can allow simpler realization of the sensorless vector controls.
