In most practical adaptive signal processing systems, e.g., active noise control, vibration and acoustic echo cancellation, substantial nonlinearities that cannot be neglected exist. this paper, we analyze the behaviors of an system in which output filter has clipping saturation-type nonlinearity by a statistical-mechanical method. We discuss dynamical steady-state performing asymptotic analysi...

The attitude synchronization tracking problem for spacecraft formation flying is investigated in this paper based on sliding-mode control and a Chebyshev neural network (ChNN). A distributed cooperative controller designed group of spacecrafts to guarantee that each individual will track the reference virtual leader presence external disturbances, system uncertainties input saturation. An adapt...

Multi-functional laser non-invasive diagnostic systems allow the study of a number of microcirculatory parameters, including index of blood microcirculation (Im) (by laser Doppler flowmetry, LDF) and oxygen saturation (StO2) of skin tissue (by tissue reflectance oximetry, TRO). This research aimed to use such a system to investigate the synchronization of microvascular blood flow and oxygen sat...

In this paper, robust adaptive tracking control is proposed for the underwater robot in the presence of parametric uncertainties and unknown external disturbances. Backstepping control of the system dynamics is introduced to develop full state feedback tracking control. Using parameter adaptation, backstepping control and variable structure based techniques, the robust adaptive tracking control...

This paper introduces a new approach for the performance analysis of adaptive filter with error saturation nonlinearity in the presence of impulsive noise. The performance analysis of adaptive filters includes both transient analysis which shows that how fast a filter learns and the steady-state analysis gives how well a filter learns. The recursive expressions for mean-square deviation(MSD) an...

The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order to design a robust autopilot in the presence of the actuator saturation, the Composite Nonli...

In this paper, a model reference adaptive control is designed for perfect tracking of moveable electrode of an electrostatic microactuator. The adaptive control of the nonlinear model of this microactuator is constituted feedback control and adaptation law. A Lyapunov function is presented that it guarantees perfect tracking and parameter convergences. The simulation shows designed adaptive con...

Recently, an adaptive posi-cast controller has been developed for dynamic systems with large time-delays. In this paper, we evaluate its performance in the context of a 4 MW combustor test-rig model that mimics many of the dynamic characteristics of an actual engine including a significant time-delay. Using closed loop input-output data and system identification, a model of the test-rig was der...
