Real-time, Low Cost Embedded De-Noising of Motor Position Control Signals
Conference proceedings(2007)
摘要
In feedback control system applications, sensor signals, often noisy, must be fed back to the controller under tight time constraints. Conventional de-noising methods were developed without considering delay, and are inappropriate for feedback loops. An embedded, short-delay signal de-noising system is suggested in this paper. The system is specifically designed to de-noise the position control signal for a sensorless switched reluctance motor, but can be extended to other applications. The results show that a significant noise reduction is achieved with a latency of 66 ns.
