A research of single-neuron nonlinear control method in boiler-turbine system

把非线性逆系统原理和单神经元自适应PID控制相结合,设计出一种新的非线性输出跟踪控制器。针对火电单元机组模型,首先用逆系统原理对该模型求取稳定逆的解,然后用单神经元自适应PID作为该系统的反馈控制器。在不同负荷下的仿真结果表明,该控制系统具有很好的抗干扰、快速响应以及稳定跟踪能力。

A new nonlinear output tacking controller has been designed in this paper, which combined the nonlinear stability inversion system theory with the single-neuron adaptation PID controller. Aimed at a model of boiler-turbine unit, at first the stability inversion solutions of model is worked out by the nonlinear stability inversion system theory, later utilize the single - neuron adaptation PID as the feedback controller of the system. Simulation results with different load - followings show that the control system is good at anti-jamming ,fast response and stability tracking capability.
