ux amplitude are decoupled by feedback; the method is called feedback linearization control (FLC).
Also, a method based on the variation theory and energy shaping, called passivity-based control
(PBC) has been recently investigated [17].
In the mid-1980s, there was a trend toward the standardization of the control systems on the basis
of the FOC methodology. However, Depenbrock, Takahashi, and Nogouchi [36] have presented a new
strategy, which abandons an idea of mathematical coordinate transformation and the analogy with DC
machine control. ese authors proposed to replace the averaging based decoupli ...
