Abstract : this paper developed time domain integral constraints on error response for siso feedback control systems caused by nominal plant ' s near cancellation of stable pole - zero near the j - axis. these integral constraints should be satisfied by any feedback control systems. these integral constraints give new insight into the inherent trade - offs. it will result in the settling time longer or the infinite norm of the error response larger when there are near cancellations of stable pole - zero near the j - axis. hence, when feedback control systems are designed, it is necessary to avoid the compensator ' s poles and zeros nearly cancelling the nominal ' s zeros and poles ( even if these poles and zeros are stable )
文摘:導出了單輸入單輸出反饋控制系統誤差響應基於名義系統穩定的零、極點近似相消的時間域積分約束，此積分約束是任何反饋控制系統均應滿足的.這一約束給出了單輸入單輸出反饋系統固有折中的新的觀點.名義系統穩定的零、極點近似相消的存在導致反饋控制系統的調節時間延長或者誤差響應的無窮范數變大.因此，在反饋控制系統設計中，盡量避免補償器的零、極點與名義系統的極、零點近似相消（即使這些零、極點是穩定的） -
In this paper, we design the imc controller using zero - pole cancellation method, and tune the controller filter parameter a according to the error e and its first difference a e and acquire the best combination between robust performance and the response speed. the error e is the difference between the reference model output and system output
