摘　　要：针对系统较为复杂的核电站稳压器,为了获得令人满意的控制效果,在生物神经内分泌腺体激素调节的原理和分数阶微积分的理论基础上,提出了一种包含长环和短环的内分泌分数阶PI~λD~μ控制器(EFOPID)。一级控制器为比例控制,能够依据系统偏差来调整二级控制器的输入,实现快速、稳定地消除偏差;二级控制器采用间接算法(Oustaloup算法)实现的分数阶PI~λD~μ控制器(FOPID),能够使系统具有更加优良的快速性、高精度性和强抗干扰能力。仿真结果表明:EFOPID比传统的比例-积分-微分控制器(PID)控制具有更加优良的性能指标和抗扰动能力。Based on the principles of biological neuroendocrine gland hormone regulation and the fractional order calculus, and considering that the pressurizer system of nuclear power plant is a very complicated system, a endocrine fractional order PI^λD^μ controller was designed with long feedback and ultra-short feedback, in order to obtain satisfactory control results. The primary controller is proportional control. According to the system errors, it can adjust the control parameters of the secondary one dynamically and eliminate the control error quickly and stably. The secondary is fractional order PI^λD^μ controller and a indirect algorithm（Oustaloup algorithm） was used to implement the fractional order controller. The system can be more excellent in velocity, precision and anti-interference ability. Simulation results show that the endocrine fractional order PI^λD^μ controller is with better performance and strong anti-interference ability than the traditional PID control.
