NettetThe basics of our non-linear control system are as follows. The chief difference is that the nonlinear design has an extra nonlinear block between the linear controller and the plant. This extra element combines with the plant to form an effectively linear system, which is controlled in the traditional manner. The inputs on the nonlinear block ...
Nonlinear control theory is the area of control theory which deals with systems that are nonlinear, time-variant, or both. Control theory is an interdisciplinary branch of engineering and mathematics that is concerned with the behavior of dynamical systems with inputs, and how to modify the output by changes in … Se mer Some properties of nonlinear dynamic systems are • They do not follow the principle of superposition (linearity and homogeneity). • They may have multiple isolated equilibrium points. Se mer An early nonlinear feedback system analysis problem was formulated by A. I. Lur'e. Control systems described by the Lur'e problem have a forward path that is linear and time-invariant, and a feedback path that contains a memory-less, possibly time-varying, static … Se mer • Lur'e, A.
