摘　　要：针对实际控制系统中恒值控制系统较多的情况,以调节性能最优为目标,利用计算机辅助分析工具和数据拟合软件,建立了继电反馈自整定所使用的PID参数整定公式。同时,针对2类常用过程模型的仿真试验,设计了一种新的整定公式并拟合得到4套整定公式,且分别用4个算例验证了4套整定公式的有效性。将新整定公式与已提出的2种整定公式进行比较,结果证明了新公式的优越性。Aiming at the condition of more constant set-point control systems in practical control systems,the new method of establishing PID tuning formula for relay feedback self-tuning by adopting computer-aided analysis tool and data fitting software is proposed for the object of obtaining optimal regulation performance.In addition,in accordance with the simulation test for two types of commonly used process models,the new tuning formula are designed and four sets of formula parameters are fitted.The validity of these four sets of tuning formula is verified using four of the computation examples.Through comparison between new tuning formula and two of the existing formula,the superiority of the new formula is incarnated.
