针对核反应堆点堆动态非线性模型 ,提出了一种非线性状态反馈的中子通量密度恒值控制的新方法。与传统的古典控制方法相比 ,此方法不必对模型进行近似线性化处理 ,因而 ,控制精度较高 ,适用的时域范围较广 ,控制律也不太复杂。仿真结果验证了这种非线性控制律的有效性和优越性 Aiming at the dynamic non-linear model of reactor reactor, a new method of non-linear state feedback control of neutron flux density is proposed. Compared with the classical classical control method, this method does not need to approximate the model linearly, so the control precision is higher, the applicable time domain is wider and the control law is not too complicated. The simulation results verify the validity and superiority of this nonlinear control law
