按照gproms例子操作了一下，但是出现了这个问题，请教各位大牛下：
1 error(s) occurred constructing the system
When performing Identity Elimination:
ERROR: variable Flowsheet.PID_controller001.set_point_external was ASSIGNed a value 0
outside the range [1000:1e+020], which is the intersection of the bounds of all
identical variables found during Identity Elimination.

variable Flowsheet.PID_controller001.set_point_exter应该是个变量值超过了边界建议修改边界或者修改模型

是的，应该是赋值超出范围了
