The inner loop USES a general proportion adjuster and the outer loop USES a single neuron PID controller with identification implement.

内回路采用常规比例调节器，外回路采用带辨识器的单神经元pid控制器。

Nowadays, single loop PID controllers are still being employed in about 80%to 90%of the control systems. However, interactions exist in many complex industry systems.

当前，生产现场控制回路约80%—90%采用单回路PID，然而在一些大型的复杂的工业生产过程中，系统的各个回路之间存在着耦合现象。
