中文摘要
      导出了单输入单输出反馈控制系统误差响应基于名义系统稳定的零、极点近似相消的时间域积分约束 ,此积分约束是任何反馈控制系统均应满足的 .这一约束给出了单输入单输出反馈系统固有折中的新的观点 .名义系统稳定的零、极点近似相消的存在导致反馈控制系统的调节时间延长或者误差响应的无穷范数变大 .因此 ,在反馈控制系统设计中 ,尽量避免补偿器的零、极点与名义系统的极、零点近似相消 (即使这些零、极点是稳定的 )
英文摘要
      This paper developed time donuin integral constraints on error response for SISO feedback control systems caused by nominal plant’s near cancellation of stable pole-zero near the j 一axis．These integral constraints should be satisfied by any feedback control systenls．These integral constraints give new insight into the inherent trade-ot~．It will result in the settling time longer or the infinite noml of the eror response larger when there are near cancellations of stable pole-zero near the j 一axis．Hence．when feedback control systems are designed，it is necessary to avoid the compensator’s poles and zeros nearly c3ncel~ the nominal’s zeros and poles(even ifthese poles and zeros are stable)．
