L 1 Gain Scheduled Adaptive Control to Water Level of Nuclear Steam Generator

This paper deals with the water level control problem of steam generators (SG) of nuclear power plants. L-1 adaptive controller design strategy employing piecewise affine linear parameter-varying model with uncertainty is illustrated. Furthermore, a gain scheduling forward compensator is introduced to further improve the anti-interference ability. The proposed controllers can ensure asymptotic stability of the closed-loop systems with guaranteed cost and L-1 tracing performance index. The numerical simulation is finally presented to demonstrate our results.
