As a major stride towards the fusion of modern control theory and conventional PID control, the newly developed active disturbance rejection control (ADRC) is of great practical significance. This paper presents ADRC applications to tackle some problems encountered in flight attitude control. The ADRC design is employed for pitch and roll attitude control. ADRC is superior in both dynamic performance...
A class of hyperchaos is modeled based on a modified smooth three-dimensional chaotic system by adding a feedback controller. The new hyperchaos has two very large positive Lyapunov exponents in a quite wide parameter region through observing the Lyapunov exponents spectra. Some simulations of the phase portraits of hyperchaotic attractors are made to show the complicated system orbits. The Poincare...
Small gain theorem is used to obtain a sufficient condition for the robust stability of continuous-time generalized predictive control (CGPC) in the presence of unmodelled dynamics. Robust bounds for CGPC can be found by evaluating control law for various selection of the available tuning parameters, and substituting into the sufficient condition. An example is given to analyze the influence of CGPC...
A new complex dynamical network based on multi-local-world (MLW) model is first introduced. Then, control of this kind of complex dynamical network by applying local feedback injections to a tiny fraction of local worlds in the whole network is investigated. Stability conditions are derived for several different dynamical network models including time-invariant networks, time-varying networks and...
