中文摘要: 研究了核电站稳压器水位控制问题.针对稳压器水位是一个时变、非线性、大惯性、多干扰的被控对象,将自抗扰控制引入到稳压器水位控制系统中,解决了传统PID超调量大、不稳定等问题.仿真结果表明,自抗扰控制在超调量等方面明显优于传统PID控制.另外,在增加外扰的情况下,自抗扰控制具有较强的抗干扰能力,证明了自抗扰控制的可行性和有效性.

Abstract:The pressurizer is a highly complex, nonlinear, and time-varying system. In order to to solve the large overshoot, instability and other issues, ADRC is introduced to the water level control of pressurizer. The simulink results illustrate that overshoot of the ADRC control is so much better than the traditional PID control. In addition, in the case of external disturbance, ADRC has strong anti-jamming capability, which illustrates the feasibility and effectiveness of the ADRC.
