【摘要】 纯滞后特性在控制对象中普遍存在,纯滞后特性控制器也可能用于对纯滞后对象进行控制,纯滞后特性还可能用于混沌控制;对纯滞后特性的工程实现进行了研究,提出了基于S7-200 PLC实现纯滞后特性的两种方法:在复数域(频域)内实现的方法和在实数域(时域)内实现的方法,并阐述了整个实现过程;最后对比了两种方法的特点。更多还原

【Abstract】 The Controlled Objects generally have pure time delay characteristic.So could design pure time delay controller to control the devices.Of course,the controller could yet identify chaos algorithm.According to application in project,this paper introduces the pure time delay characterisitic,and gives two ways which are both frequence domain model and time domain model to gain the charcterisitic on S7-200 PLC,compares control process and features of the two ways.更多还原
