有一个3阶对象，要求使用继电自整定方法对其实施自适应PID控制。 要求： 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (A 3-order object, requires the use of relay self-tuning PID control methods on the implementation of adaptive. Requirements: 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)

用MATLAB实现欧式距离，很简单的例子，一学就会。其中，还求出了距离的最小值。希望大家可以相互学习一下。(Very simple example, a study will Euclidean distance, using MATLAB. Wherein the minimum distance is obtained. I hope we can learn from each other.)

控制规律的选用要根据过程特性和工艺要求来选取，决不是说PID控制规律在任何情况下都具有较好的控制性能，不分场合都采用是不明智的。如果这样做，只会给其它工作增加复杂性，并给参数整定带来困难。当采用PID控制器还达不到工艺要求，则需要考虑其它的控制方案。如串级控制、前馈控制、大滞后控制等。 (Choice of control law according to process characteristics and process requirements to select, does not mean that PID control law in any case have a better control performance, are used regardless of where it would be unwise. If you do, will only add to the complexity of other work, and to the parameter tuning difficult. When using the PID controller has not yet reached technological requirements, you need to consider other control options. Such as cascade control, feedforward control, large time delay control.)
