Model Free Adaptive Control

Model Free Adaptive Control (MFAC) is a novel adaptive control method for unknown discrete-time nonlinear systems with time-varying parameters and structure. It relies solely on measured input and output data, making it applicable for practical plants. This book covers new concepts, dynamic linearization approaches, control system design methods, stability analysis, and applications of MFAC. It also discusses related issues such as MFAC for complex systems, modularized controller designs, robustness, and symmetric similarity. The book is aimed at researchers, senior undergraduates and graduate students in engineering and applied sciences, and professional engineers in process control.

Model Free Adaptive Control: Theory and Applications summarizes theory and applications of model-free adaptive control (MFAC). MFAC is a novel adaptive control method for the unknown discrete-time nonlinear systems with time-varying parameters and time-varying structure, and the design and analysis of MFAC merely depend on the measured input and output data of the controlled plant, which makes it more applicable for many practical plants. This book covers new concepts, including pseudo partial derivative, pseudo gradient, pseudo Jacobian matrix, and generalized Lipschitz conditions, etc.; dynamic linearization approaches for nonlinear systems, such as compact-form dynamic linearization, partial-form dynamic linearization, and full-form dynamic linearization; a series of control system design methods, including MFAC prototype, model-free adaptive predictive control, model-free adaptive iterative learning control, and the corresponding stability analysis and typical applications in practice. In addition, some other important issues related to MFAC are also discussed. They are the MFAC for complex connected systems, the modularized controller designs between MFAC and other control methods, the robustness of MFAC, and the symmetric similarity for adaptive control system design. The book is written for researchers who are interested in control theory and control engineering, senior undergraduates and graduated students in engineering and applied sciences, as well as professional engineers in process control.
