a nonlinear system (or a non-linear system) is a system in which the change of the output is not proportional to the change of the input. Nonlinear problems...

types of nonlinear systems. Historically, system identification for nonlinear systems has developed by focusing on specific classes of system and can be...

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...

In mathematics and particularly in algebra, a system of equations (either linear or nonlinear) is called consistent if there is at least one set of values...

Jacobian matrix J+ = (JTJ)−1JT instead of the inverse of J. If the nonlinear system has no solution, the method attempts to find a solution in the non-linear...

a nonlinear system is a system that is not linear—i.e., a system that does not satisfy the superposition principle. Less technically, a nonlinear system...

applies to more real-world systems because all real control systems are nonlinear. These systems are often governed by nonlinear differential equations....

symmetric. Linear dynamical systems can be solved exactly, in contrast to most nonlinear ones. Occasionally, a nonlinear system can be solved exactly by...

chaos, describes how a small change in one state of a deterministic nonlinear system can result in large differences in a later state (meaning there is...
