For a PID controller designed based on the ISTE criterion, as in Sect. 3, the parameters are Kc*=0.648, Ti*=9.050 and Td * =2.332, which yield PI-PD parameters of Kp=0.108, Ti =1.508, Kf =0.540 and Td =2.798. The closed-loop performances to a unity step set-point change and a disturbance with a magnitude of
0.5 introduced at time t=50 s are shown in Fig. 12. The PID-P and PID designs based on the ISTE have very similar response characteristics, whereas the PI-PD design gives almost no overshoot. Note that the disturbance responses of the PID and PI-PD are the same as explained above and better than the disturbance rejection of the PID-P. Example 4 Here, the performance of a PID-P controller suggested by Park et al. [2] for controlling
unstable processes is compared with a PI-PD controller using their suggested unstable plant transfer function of G(s)=4 exp(
2s)/(4s
1). Their controller parameters were Kc=0.068, Ti=1.885, Td=4.296 and Kf=0.350. A PID controller designed using the ISTE criterion gives parameters Kc*=0.627, Ti*=8.143 and Td * =0.978, and
the corresponding PI-PD controller parameters are Kp=0.105, Ti=1.357, Kf=0.522 and Td=1.174. The closed-loop performances with these controllers are shown in Fig. 13 for a unity step set-point change and disturbance with a magnitude of
0.5 introduced at time t=50 s. The PI-PD controller has a smaller overshoot. Again, the disturbance rejection of the PID and PI-PD is the same and better than the disturbance rejection of the PID-P structure.

对于PID控制器设计的基础上，教育技术协会的标准，如教。 3，参数架KC *= 0.648，钛*= 9.050和Td * = 2.332，它的收益率的PI -局部放电克雷伯= 0.108，钛= 1.508，钾长石= 0.540和Td = 2.798参数。闭环表演，一个团结的一步设定点变化，干扰与数量级？0.5在时间t = 50 s是如图介绍。 12。的PID - P和设计的PID教育技术协会的基础上有非常相似的响应特性，而皮光探测器的设计提供了几乎没有过冲。请注意，PID和扰动响应有价证券- PD的是一样的解释，上述比更好的PID抗干扰磷。例4在这里，一个PID性能磷控制器建议的公园等。 [2]控制
不稳定的过程是与一个pi - PD控制器使用他们的建议，不稳定的植物的G（s）兰4进出口（？2秒）/（4型？1）传递函数。他们的控制器参数，陈家= 0.068，钛= 1.885，运输署和KF = 4.296 = 0.350。 PID控制器的设计采用标准的教育技术协会提供的参数陈家*= 0.627，钛*= 8.143和Td * = 0.978，和
相应的PI - PD控制器参数克雷伯= 0.105，钛= 1.357，钾长石= 0.522和Td = 1.174。封闭与这些控制器循环表演，如图。 13 1级的统一步骤设定点的变化和干扰？0.5推出的时间t = 50号在PI - PD控制器具有较小的超调。同样，该PID和有价证券扰- PD是相同的，比PID的干扰抑制磷结构更好。
