The conventional water level controller for nuclear steam generator is challenged in all working conditions variations.Thus

a nonlinear steam generator sliding mode controller based on genetic algorithm was proposed with easy engineering implementation in this article.Through MATLAB simulation test

the water level control effect of this sliding mode control methodology was observed

and its anti disturbance ability was verified.Moreover

performance comparisons between this sliding model controller and the conventional PID controller were carried out.The results indicate that

compared with the conventional PID controller

the proposed sliding mode controller based on genetic algorithm possesses a more stable rapid tracking reaction and potential in anti-disturbance within the whole working conditions.The proposed controller also has faster response characteristics and shorter regulating time under low power condition

which has positive engineering application significance.
