摘　　要：核电作为一项绿色能源,已经被很多国家广泛使用,且压水堆核电站占其中大部分。稳压器是压水堆核电站中的重要设备,它的功能是保证一回路中的压力和水位在额定值附近,从而确保运行的安全性和经济性。稳压器是有时间滞后、容易受较多干扰、非线性的复杂系统。传统的PID由于自身的缺陷,无法达到较优的控制效果。文章通过研究生物免疫系统的反馈调节,设计出具有自适应的免疫PID控制器。根据MATLAB仿真结果表明,相对于传统的PID控制器,免疫PID控制器具有更好的稳定性,减小了超调量,缩短了调控时间,具有更好的动态调节效果。As a green energy,nuclear power has been widely used in many countries,and pressurized water reactor(PWR)nuclear power plants account for most of them.Voltage regulator is an important equipment in PWR nuclear power plant.Its function is to ensure that the pressure and water level in the primary circuit are near the rated value,thus ensuring the safety and economy of operation.Voltage regulator is a complex system with large time delay,nonlinear,interference.Due to its own limitations,the traditional PID can not achieve better control effect.In this paper,the adaptive immune PID controller is designed by studying the feedback regulation of biological immune system.According to MATLAB simulation results,compared with the traditional PID controller,the immune PID controller has better stability,reduced overshoot,shortened regulation time,and has better dynamic regulation effect.
