摘要
利用过程的标准化死区时间修正基于给定增益裕度和相位裕度整定的PID(比例积分微分控制器)的积分时间常数,并通过曲线拟合最小二乘法求得积分时间常数的修正公式.仿真结果表明对于大滞后过程该方法具有良好的控制性能和鲁棒性.
The integral action time is revised by the normalized dead-time of the process for the PID controller which is tuned to meet user-specified gain margin and phase margin. Furthermore, the revised formula of the integral action time is obtained from the curve fitting in the least-squares sense. Simulations show that the proposed method can provide better performance and Robustness for the process with a large delay time.
