摘要:
Digital control based on a phase-locked loop technique is presented. The key to this control is up/down counting. A dynamical model is given which links up/down counting with integrative control. The addition of proportional-derivative or similar algorithms is suggested to improve the control performance. A variation of the Åström-Hägglund methods is developed as a tuning procedure. Some comments are made on the sampling effects
