带simth补偿的pid控制器主要用于纯滞后系统的pid温度控制，属于改进型的pid控制器。本simulink仿真为毕业设计内容，运行效果良好。本例设定温度200度，参数之类可以根据需要自由修改-Smith compensation with pid controller mainly used for pure delay systems pid temperature control, are improved pid controller. The simulink simulation content for the graduation project, run well. In this case temperature of 200 degrees, like the parameters can be modified according to need freedom
