This open access book presents a pioneering methodology that addresses these limitations, offering a mathematically rigorous and practically effective alternative to conventional state-space models, given that the study of nonlinear control has faced significant challenges, particularly in the explicit determination of control vectors for complex multi-input multi-output (MIMO) systems. 

Authored by the proposer of the Fully Actuated System (FAS) approach, this book systematically establishes a new paradigm for the analysis and design of dynamical control systems....
