In this paper, a new, robust control method based on a multimodel predictive control scheme is developed for steam generator level (SGL) control in nuclear power plants. For a multiramp power increase from low to full power, the proposed controller is capable of keeping the SGL within the admissible range by minimizing the level transients and improving the stability of the control loop. Simulation results and a general framework for systematically studying the SGL are presented to demonstrate the effectiveness of the proposed control method by comparing the performance of the designed controller with that of a properly tuned conventional three-element proportional-integral-derivative (PID) controller. Moreover, it has been demonstrated that the proposed controller is more robust than a conventional PID controller to steam flow disturbances caused by load variations.
