In this paper, the robust adaptive control scheme based on adaptive backstepping design is used to control the autonomous second order strict feedback form such as the Lorenz Chaotic system. The design procedure is recursive; at the i step, the i subsystem is stabilized with respect to a Lyapunov function Vi by the design of a stabilizing function αi, tuning function τi, and the update law ̇̂ θi ...

In view of the issue of rapid attitude maneuver control of agile satellite, this paper presents an attitude-tracking control algorithm with path planning based on the improved genetic algorithm, adaptive backstepping control as well as sliding mode control.

In this paper, an adaptive backstepping technique based fault tolerant control scheme is developed for a spacecraft attitude stabilization system, in which the external disturbances and partial loss of actuator effectiveness fault are considered. More specifically, using the adaptive backstepping control method, a baseline control law is first proposed for the normal system without actuator fau...

In this paper, we consider controlling a class of single-input-single-output (SISO) commensurate fractional-order nonlinear systems with parametric uncertainty and external disturbance.

In this paper, an adaptive fuzzy backstepping output feedback control approach is proposed for a class of strict-feedback stochastic nonlinear systems with time delays and immeasurable states. Fuzzy logic systems are firstly utilized to approximate the unknown nonlinear functions, and then a fuzzy state observer is designed to estimate the immeasurable states. By combining the fuzzy adaptive co...

Compliant actuators are significant for safe physical human–robot interaction. Series elastic actuator (SEA) is the most popular type of compliant actuators, which possesses several attractive features, such as low output impedance, back drivability, shock tolerance, smooth force transmission, and energy efficiency. This brief focuses on the adaptive command-filtered backstepping control (CFBC)...

In this paper, we study the tracking control problem for a nonlinear system in which the zero dynamics may be unstable.
