摘要(Abstract)：

新型电力系统中，由于新能源发电占比不断攀升且其具有强烈的不确定性，抗扰动成了火电机组功率控制的核心任务。目前火电厂功率控制系统仍然采用PID控制，难以满足火电机组深度、连续、频繁调峰调频的需求。为了使先进控制理论更好地应用于火电机组功率控制，借力PID控制的工程基础实现了线性自抗扰控制（LADRC）的平滑应用。通过分析LADRC的结构以及反馈环的传递函数，得出了LADRC的PID实现形式，并通过Simulink仿真进行验证。仿真及工程应用测试表明，LADRC的PID实现继承了自抗扰控制突出的扰动抑制能力。在相同的PID及相关参数下，LADRC的PID实现对各类扰动都具有突出的抑制能力，其中三阶LADRC的扰动抑制能力最强、调节速度最快。LADRC的PID实现能够满足火电机组功率控制系统的需求，控制品质优于常规PID控制。LADRC的PID实现扩展了LADRC的工程应用空间。
