| Abstract: | A mathematics model of speed observer of direct torque control (DTC) system is derived , and a DSP-based speed-sensorless DTC system is designed and tested. It exhibits extremely fast torque response, which is 0.86ms for a nominal torque step. The accuracy of shaft speed estimate is very good, which reaches 0.5% above 100r/min. This system is used extensively in aircraft due to its excellent performance and reliability.-= |
