A Novel Nonlinear Fault Tolerant Control for Manipulator under Actuator Fault
Mathematical Problems in Engineering, 2018 A fault tolerant control (FTC) scheme based on adaptive sliding mode control technique is proposed for manipulator with actuator fault. Firstly, the dynamic model of manipulator is introduced and its actuator faulty model is established. Secondly, a fault tolerant controller is designed, in which both the parameters of actuator fault and external ...

Fault Estimation and Fault-Tolerant Control of Wind Turbines Using the SDW-LSI Algorithm
IEEE Access, 2016 The dynamic response of the pitch angle slows down when the pitch actuator of wind turbines fails, and the fault leads to fluctuations in the generator speed and in the output power.

Finite‐time robust fault‐tolerant control against actuator faults and saturations
IET Control Theory & Applications, 2017 The finite‐time robust fault‐tolerant control problem is addressed for a class of perturbed linear systems with actuator faults and input amplitude saturations. A compensation control strategy is proposed to eliminate the effects of actuator faults and non‐linear disturbance‐like inputs within a finite‐time, as well as to ensure the control inputs be ...

Advanced Functional Materials, EarlyView.Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...
