| Abstract |
Sensorless servo control requires fast, on-line rotor position estimation during standstill. This paper
presents a way to calculate a position estimate in every PWM cycle. It uses a test signal with full
PWM frequency. A decoupling algorithm eliminates the effect of fast current changes on the position
estimates. Measurements of position command tracking and transient load behaviour are shown. |
