摘要: In this paper, a spatial control strategy based on Fast Output Sampling (FOS) technique is proposed for Advanced Heavy Water Reactor (AHWR). The non-linear model of AHWR, represented by 90 first order differential equations having 5 inputs and 18 outputs, linearized to obtain standard state-space representation. Using similarity transformation, the original higher order, ill-conditioned discrete system AHWR decomposed into two comparatively lower subsystems, namely, `slow' `fast' subsystem orders 73 17 respectively. Now, state feedback controls are designed separately slow fast then composite controller obtained using these individual controls, which realized FOS gain. Thus, states not required feedback. efficacy has been demonstrated simulation transient behavior AHWR. Performance found be satisfactory.
