Abstract:
For the presence of large delay,large inertia and large overshoot phenomenon of the No.2 steam temperature of 600 MW boiler of an electric power limited liability company,a single-neuron self-adaptive proportional sum differential(PSD)switching control scheme is proposed here.A common PID controller is applied to inner loop.Outer loops use appropriate switching between single-neuron self-adaptive PSD control and PID control.Configuration of the undisturbed switching control scheme is designed based on the distributed control system platform of Foxboro I/A series.The simulation results from the software of advanced process platform designed in the lab illustrate that the proposed control scheme has the high performance of small overshoot(less than 2%),short tuning time and strong robustness.Practical application shows that the method has good dynamic quality adjustment and control effectiveness.
