说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

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.)
