比例-积分-导数（PID）控制器由于减少了需要调整的参数数量，在工业控制系统中得到了广泛的应用。最流行的设计技术是齐格勒-尼科尔斯方法，它完全依赖于从植物阶跃响应中获得的参数。然而，除了只适用于具有单调阶跃响应的系统外，根据齐格勒-尼科尔斯方法调谐控制器的补偿系统通常具有高超调率的阶跃响应。本文提出了比例积分（PI）和PID控制器的整定方法，与齐格勒-尼克尔斯方法一样，只需要从植物阶跃响应中获得参数。该方法还包括为具有欠阻尼阶跃响应的装置设计PID控制器，并提供系统调整控制器增益的手段，以满足瞬态性能规范。此外，由于该方法的所有发展完全依赖于基于频域的控制课程中引入的概念，因此本文也具有教学贡献。
Proportional-integral-derivative (PID) controllers are widely used in industrial control systems because of the reduced number of parameters to be tuned. The most popular design technique is the Ziegler-Nichols method, which relies solely on parameters obtained from the plant step response. However, besides being suitable only for systems with monotonic step response, the compensated systems whose controllers are tuned in accordance with the Ziegler-Nichols method have generally a step response with a high-percent overshoot. In this paper, tuning methods for proportional-integral (PI) and PID controllers are proposed that, like the Ziegler-Nichols method, need only parameters obtained from the plant step response. The methodology also encompasses the design of PID controllers for plants with underdamped step response and provides the means for a systematic adjustment of the controller gain in order to meet transient performance specifications. In addition, since all the development of the methodology relies solely on concepts introduced in a frequency-domain-based control course, the paper has also a didactic contribution.
