Chaos of Hydro-turbine Governing System and Its Control
摘要
Abstract
In order to study the nonlinear dynamics behavior of hydro-trubine governing system, the chaotic complex dynamic characteristics of hydraulic turbine governing system were analyzed, including the space trajectory, the Lyapunov exponent and the Poincare map. These characteristics indicate that the dynamical system contains chaotic attractor. In order to eliminate the chaotic vibration, the system could be controlled to any fixed point and any periodic orbit by means of sliding mode method and MATLAB simulations were presented to confirm the effectiveness of the controller. The results show that using sliding mode method can make the system track target orbit strictly and smoothly with short transition time. It also provides a reference for relevant chaos control in other hydraulic turbine governing.关键词
