Application of fuzzy model predictive control to a drum-boiler

“…The difficulties in designing a drum level controller arise from the following factors: reverse dynamics, or non-minimum phase behavior due to swell and shrink effects, particularly at low power; changes in plant dynamics with operating power; dynamics uncertainties; corrupted feed-water flow measurement signal with biased noises [5].…”

The paper discusses a TS fuzzy model identification method for an industrial drum-type boiler plant using the fuzzy clustering approach. The fuzzy model is constructed from a set of input-output data that covers a wide operating range of the plant. Then this paper studies the application of GPC algorithm in drum level control system Based on the T-S fuzzy model, simulates the control effect of the controller in the MATLAB environment, and analyze the performance of the control system.

Abstract:Poor control of steam generator water level is the main cause of unexpected shutdowns in nuclear power plants. Particularly at low powers, it is a difficult task due to shrink and swell phenomena and flow measurement errors. In addition, the steam generator is a highly complex, nonlinear and time-varying system and its parameters vary with operating conditions. Therefore, there is a need to systematically investigate the problem of controlling the water level in the steam generator in order to prevent such costly reactor shutdowns. The objective of this paper is to design, evaluate and implement a water level controller for steam generators based on a fuzzy model predictive control approach. An original concept of modular evolved control system, seamless and with gradual integration into the existent control system is proposed as base of implementation of the presented system.
