Notes on log linearization
WebLog-linearization means taking the log-deviation around a steady state value. Assume x denotes the steady state value of variable x t.Next,define the log-deviation of variable x t … WebFeedback linearization is a common strategy employed in nonlinear control to control nonlinear systems. Feedback linearization techniques may be applied to nonlinear control systems of the form. [1] (1) where is the state, are the inputs. The approach involves transforming a nonlinear control system into an equivalent linear control system ...
