Convenient Almost Optimal and Robust Tuning of Pi and Pid Controllers
نویسندگان
چکیده
T uningrules for PI and PID controllers for stable non oscillating plants are presented. These rules are based on an optimization procedure, where both low frequency performance, mid frequency stability margins and high frequency control activit y are taken into account. The required plant kno wledgeis either a speci c frequency point, like in Ziegler-Nichols frequency design method, or a step response for a rst order plant with time dela y.Almost optimal tuning rules are presented based on this knowledge, both for PI and PID controllers.

Optimal Robust Tuning for 1DoF PI/PID Control Unifying FOPDT/SOPDT Models
The aim of the paper is to present tuning equations for one-degree-of-freedom (1DoF) proportional integral (PI) and proportional integral derivative (PID) controllers. These are based on a performance/robustness trade-off analysis with firstand second-order plus deadtime models. On the basis of this analysis a tuning method is developed for 1DoF PI and PID controllers for servo and regulatory c...
متن کاملOffline Auto-Tuning of a PID Controller Using Extended Classifier System (XCS) Algorithm
Proportional + Integral + Derivative (PID) controllers are widely used in engineering applications such that more than half of the industrial controllers are PID controllers. There are many methods for tuning the PID parameters in the literature. In this paper an intelligent technique based on eXtended Classifier System (XCS) is presented to tune the PID controller parameters. The PID controlle...

This paper’s aim is to present a tuning approach for full Two-Degree-of-Freedom (2-DoF) PI and PID controllers for First-Order-Plus-Dead-Time (FOPDT) and Second-OrderPlus-Dead-Time (SOPDT) controlled processes. The tuning relations provide the value of the typical parameters for a PID controller plus the set-point weighting factor, being these relations driven by just one single design paramete...

متن کاملA New Approach to the Robust Pid Controller Synthesis for Systems with Unknown Mathematical Model
The presented paper deals with a new engineering method applicable to real plants with unknown mathematical model and varying parameters. Most of the existing 150 to 200 engineering PI(D) controller design methods are closely associated with the knowledge of the structure and parameters of the controlled plant [1], [2]. If neither the mathematical model of the controlled plant nor its parameter...
