摘　　要：提出了一种根据闭环系统在阶跃扰动作用下输出波形的某些特征值，直接对ＰＩＤ调节器参数进行自动整定的方法。本方法所需的被控对象的先验知识少，且无需对系统加入人为的扰动信号，适用于工业实时控制。文中给出仿真实例说明本法的性能。A self-tuning method of PID controller based on the features of the closed - loop transient response caused by step load disturbance is proposed in this paper. Since which requires minimal prior information on the controlled process and the controller can be tuned automatically according to system response under natural load disturbance, it is not necessary to apply a disturbance signal to system intentionally. For itsperformance, some simulation examples are given in this paper.
