【Abstract】 The definition and classification are given for the several existing model-free control (MFC) methods. A brief review on the state of the art for the model-free adaptive control (MFAC) is presented and the difference between MFAC and other mainstream control methods is discussed in this paper. TWo practical modularized control system design schemes are proposed by adding MFAC into the existing model-based control schemes for enjoying the extra performance improvement from MFAC. Some prospective research topics are also listed in this work.更多还原
