As a reactor core has time-varying and nonlinear characteristics, it is difficult to achieve an ideal control effect with traditional control theory. To optimize the core power control performance, a compound control scheme is formulated that is composed of multiple controllers by weighting and switching. Firstly, the nonlinear model of a reactor core is transformed into a transfer function model. With the triangular membership function, five transfer function models under different core powers are weighted to establish the core fuzzy multimode...
