摘要

The boiler-turbine coordinated control system in power station has the characteristics of multi-variables, nonlinear, time-varying, coupling and large time-delay etc, and the performance of the boiler-turbine control system has great impact on the safety and economy of a power unit Biology immune system is characterized by its strong robustness and self-adaptability even when encountering amounts of disturbances and uncertain conditions.To overcome the effects of nonlinear behavior and coupling of energy feed-demand for boiler-turbine coordinated control system, prompted by the regulation rule of biology immune feedback mechanism, aiming at a class of 160MW nonlinear boiler-turbine system model, a control strategy for boiler-turbine coordinated system based on immune feedback mechanism is presented in this paper.Simulation results for different loads of boiler-turbine system show that the control strategy has a better decouple and disturbance rejection ability.
