Research Design Of An Adaptive Controller Based On Desired Trajectory Compensation Of Neural Networks

open access: yesCybernetics and Information Technologies, 2014
This paper has designed a variable structure controller based on the nominal compensation of neural networks. The neural network input is the desired trajectory, which eliminates the strict assumptions of the control inputs in conventional neural ...

Design of Discrete-Time Backstepping Sliding- Mode Control for LCL-Type Grid-Connected Inverter

open access: yesIEEE Access, 2020
This study designs a discrete-time backstepping sliding-mode control (DTBSMC) method for an LCL-type grid-connected inverter. Firstly, the dynamic model of a discrete-time three-order system is derived, and a discrete-time backstepping control method ...

Rapid-Erection Backstepping Tracking Control for Electrohydraulic Lifting Mechanisms of Launcher Systems

open access: yesApplied Sciences, 2022
Uncertainties and disturbances widely exist in electrohydraulic lifting mechanisms of launcher systems, which may worsen the rapid-erection tracking accuracy and even make the system unstable.

Adaptive Backstepping Sliding Mode Control for Boost Converter With Constant Power Load

open access: yesIEEE Access, 2019
The negative impedance characteristics of a constant power load (CPL) can easily lead to the instability of the DC bus voltage. To improve the stability of the DC bus voltage, an adaptive backstepping sliding mode control strategy for a boost converter ...

Point-to-point control of a 2R planar horizontal underactuated manipulator [PDF]

open access: yes, 2006
This paper presents a control strategy for a two-link manipulator with revolute joints (2R) with an unactuated second joint, wherein the motion of the system is confined to a horizontal plane. The model takes into account the frictional forces present in
