In this paper, a derivative Lorenz chaotic system is considered and the stability of equilibrium points and the existence of Hopf bifurcation are investigated by center manifold theorem and normal form theory. Besides, we designed a washout controller such that the derivative Lorenz chaotic system undergoes a controllable Hopf bifurcation. By the calculation of the first Lyapunov coefficient and adjust...
An improved included angle division method is proposed for Hammerstein systems. In this division method, nonlinearity of the system is taken into account to distribute gridding points, so distribution is more reasonable and computation load in division is reduced greatly. Based on the division result, a multimodel predictive controller is designed to overcome the drawbacks of the common nonlinearity...
