摘　　要：提出了一种新的积分器,并同线性积分器、Clegg积分器和王勇积分器进行了比较分析和仿真。它利用MATLAB符号数学工具箱中函数计算了积分器的谐波数据,利用其Simulink建立了各积分模块,方便连接成控制系统仿真。分析和仿真发现,新积分器相位滞后小,具有消除稳态余差能力。而Clegg积分器和王勇积分器不能消除稳态余差,仅应用在特定对象中。A new integrator is proposed, and its analyzing and simulating are compared with linear integrator, Clegg抯 integrator and Wangyong抯 integrator in the paper, harmonic data of each integrator are calculated by using symbolic tool functions in Matlab.Its module is built based on Simuluink in order to simulating conveniently. After this, we found that three non-linear integrator has lesser phase lag than linear integrator, but only the new integrator can eliminate a steady state抯 error while Clegg抯 and Wangyong抯 integrator can not, which only is used in controller on particular plants.
