L1 Adaptive Output Feedback Controller for Nonlinear Systems in the Presence of Unmodelled Dynamics
نویسندگان
چکیده
This paper presents the L1 adaptive output feedback controller for a class of uncertain nonlinear systems in the presence of time and state dependent unknown nonlinearities, and multiplicative unmodeled dynamics. The L1 adaptive controller ensures uniformly bounded transient and asymptotic tracking for system’s both signals, input and output, simultaneously. The performance bounds can be systematically improved by increasing the adaptation rate.

L1 Adaptive Controller for Nonlinear Systems in the Presence of Unmodelled Dynamics: Part II
This paper presents a novel adaptive control methodology for a class of uncertain nonlinear systems in the presence of unmodelled dynamics. The adaptive controller ensures uniformly bounded transient response for system’s both input and output signals simultaneously. The performance bounds can be systematically improved by increasing the adaptation gain.
متن کاملRobust adaptive control of nonlinear systems with unmodelled dynamics
A robust adaptive output feedback controller is proposed for a class of nonlinear systems represented by input–output models. In the design of the adaptive controller, a signal is used to characterise the unmodelled dynamics and a nonlinear damping term is introduced to counteract the effects of the unmodelled dynamics and bounded disturbances. With the proposed controller, all the variables in...
متن کاملADAPTIVE FUZZY OUTPUT FEEDBACK TRACKING CONTROL FOR A CLASS OF NONLINEAR TIME-VARYING DELAY SYSTEMS WITH UNKNOWN BACKLASH-LIKE HYSTERESIS
This paper considers the problem of adaptive output feedback tracking control for a class of nonstrict-feedback nonlinear systems with unknown time-varying delays and unknown backlash-like hysteresis. Fuzzy logic systems are used to estimate the unknown nonlinear functions. Based on the Lyapunov–Krasovskii method, the control scheme is constructed by using the backstepping and adaptive techniqu...
متن کاملModified L1 Adaptive Control Design for Satellite FMC Systems with Actuators Time Delay
A modified method for satellite attitude control system in presence of novel actuators is proposed in this paper. The attitude control system is composed of three fluidic momentum controller (FMC) actuators that are used to control Euler angles and their dynamics is considered in satellite attitude equations as well. L1 adaptive control is utilized for satellite three-axial ...
متن کاملL1 Adaptive Output Feedback Controller for Minimum Phase Systems
This paper presents an L1 adaptive output feedback controller for a class of uncertain nonlinear systems in the presence of time and output dependent unknown nonlinearities. As compared to earlier introduced L1 adaptive output feedback control architectures, the architecture in this paper relies on system inversion, and is therefore limited to minimum phase systems. Similar to prior solutions i...
