Since the dynamics of a linear system is much simpler than that of a nonlinear system, if a nonlinear (control) system can be converted into a linear (control) system, the analysis and design tools for linear (control) systems can then be used. Hence different kinds of linearizations ...

Feedback linearization of anonlinear systemis to find a nonsingular feedback and a state transformation such that the closed-loop system is linear in the new state coordinates. For the nonlinear control systems with disturbance, the feedback linearization problem is difficult to solve, because we ...
Particularly, the interesting fact in following is obtained: affine nonlinear control systems with some kinds of symmetric structure can not be exactly linearized via state feedback. 参考文献(共5条): [1] 程代展 秦化淑.非线性控制系统的拓扑结构[J].自动化学报,1991,17(2):129-136,. [2] 赵军,...

In this paper we address the problem of linearization of nonlinear control systems using coordinate transformations. Although necessary and sufficient geometric conditions have been provided in the early eighties, the problem of finding the linearizing coordinates is subject to solving a system of partial...
The paper presents a novel fuzzy feedback linearization control of nonlinear multi-input multi-output (MIMO) systems for the tracking and almost disturbance decoupling (ADD) performances based on the fuzzy logic control (FLC). The main contribution of this study is to construct a controller, under...

The paper proposes the full linearization of nonlinear characteristics of flow control valves via variable gear ratio design. The inherent nonlinear function of the normalized valve capacity coefficients to the percentages of valve opening is derived fro
