Abstract

The invention discloses a passive control method of a four-order chaotic power system. The control scheme is as follows: the researched four-order chaotic power system is equivalent to a passive system through mathematical deduction according to the passivity control theory, and a state feedback controller of the chaotic dynamics system is designed on the basis so as to realize the gradual stability of the minimum-phase chaotic system and a weak minimum-phase chaotic system at a balance point. Compared with the existing control method, the passive control method of the four-order chaotic power system disclosed by the invention can be used for performing switch control on the chaotic motion in the power system to finally eliminate the chaotic phenomenon in the power system, and effectively reducing the harm of self-excited oscillation of the system in the control process to realize the fast and stable operation of the system.

Description

technical field

[0001] The invention belongs to the field of nonlinear system control, in particular to a passive control method of a fourth-order chaotic power system. Background technique

[0002] Chaos is a deterministic non-linear system whose trajectory is very complex but not completely random, and the existence of chaos can be observed in many cases. The dynamical characteristics of chaos have proven to be very useful in describing and quantifying a large number of complex phenomena. However, due to the complexity and singularity of the chaotic system, the research of chaos control theory is more challenging, and the research and development of this field has become a research hotspot in contemporary nonlinear science.

[0003] The seemingly random nature of chaotic motion makes most of the existing nonlinear system analysis and control methods quite unreliable, and there are few control methods that can be used in practical systems, and there is a lack of more effec...
