The single-neural cascade control system of intelligent switch regulating devices and its application

A regulating device which consists of a main regulator, sub-regulator and regulating valve, is proposed. The control device has a structure of double-loop cascade control that can realize intelligent switching. At the same time, a supervisory Hebbian rule based single-neural PSD adaptive controller is designed for the controlled objects with nonlinear parameter loads. Under the condition of configuration using the functional blocks of Bailey Controls´ CLC-04 programmable regulator, we controlled the reheated steam temperature of the 670T/H boiler at the 200 MW Shanxi Shentou power plant unit for 78 hours. The results obtained indicate that the single-neural cascade compound control system, which consists of an intelligent switch for the regulating devices, gives good controllability and robustness
