摘要
Abstract
A data-based proportional integral derivative (PID) controller design method was intro- duced. In this method, the PID controllers were designed from the process input and output data col- lected in an open-loop test, without resorting to the availability of a process model preceding the con- troller design and trial-and-error procedure necessitated in the model-based PID design. By extending the Virtual Reference Feedback Tuning (VRFT) design to continuous time systems, the PID parame- ters were obtained by a least square solution of the optimization problem formulated in the frequency domain. As the specification of closed-loop reference model is important for the data-based PID de- sign, the reference model can not be chosen arbitrarily. To investigate the effect of reference model on the data-based PID design, two reference models were used to design the PID controllers and the sim- ulation results were compared. It was shown that the PID designs using the two reference models pro- vided comparable control performance.关键词
