The parameters self-tuning algorithm of PID controller based on the relay feedback is mostly used in the simple speed regulation systems, and it has not been applied in the AC vector speed regulation system yet. The Z-N formula is introduced, and the parameters self-tuning algorithm based on relay feedback is analyzed in detail, and then a group of formulas which suit for engineering applications is also deduced. Moreover these formulas are applied to PI parameters self-tuning in AC vector speed regulation system. The experiment shows that the self-tuning formulas take a good performance, and greatly improves the tuning efficiency of PI parameters in the AC vector speed regulation system.
