Abstract

The invention provides an auto-disturbance-rejection control method used for nuclear reactor power. Aiming at a problem that a current nuclear reactor object has no controller which is simple and can achieve a good control effect, the invention provides a method of using an auto-disturbance-rejection controller in nuclear reactor power control. Through derivation, an original model is converted into a non-linear model suitable for designing the auto-disturbance-rejection controller. Model information is fully used and an ESO burden is mitigated. A characteristic that system output y is measurable is used so that the auto-disturbance-rejection controller based on RESO is designed. Finally, through simply adjusting a bandwidth, a controller parameter can be easily obtained. Compared to advanced control algorithms of prediction control, fuzzy control and the like, the control system has a simple structure and a good control effect.

Description

technical field [0001] The invention belongs to the control field of nuclear power plants, and in particular relates to an active disturbance rejection control method for nuclear reactor power. Background technique [0002] Nuclear power plants are highly complex nonlinear systems whose parameters are functions of operating power, nuclear fuel burnout and control rod values, and vary with time. In load-following conditions, when large power fluctuations occur, special consideration must be given to the effects of these factors. Most of the existing reactors are controlled by conventional regulation systems, which are designed according to the parameters of the base load operating point. The three-channel nonlinear controller usually used in PWR is actually a PID controller with nonlinear gain compensation. However, the regulation performance of conventional controllers is challenged under large load fluctuations. Many other advanced process control methods are also emergi...
