A study of position sensorelss control for IPMSM having non-sinusoidal inductance spatial distribution based on pattern matching method

A pattern matching method for position sensorless control of IPMSMs having non-sinusoidal inductance spatial distribution in standstill and very low speed region has been proposed. In the proposed method, the rotor position is estimated by comparing the phase current derivatives measured in a real-time with those in advanced. The current derivatives are… CONTINUE READING
