In this work, an event-triggered adaptive robust controller (ET-ARC) design is considered for a continuous-time nonlinear system combined with structural uncertainties and parameter uncertainties. In the event-trigger scheme, the controller only can obtain the sampled date of the output measurement at some certain instants determined by the designed triggering condition and therefore the performance...
A backstepping method based adaptive robust dead-zone compensation controller is proposed for the electro-hydraulic servo systems (EHSSs) with unknown dead-zone and uncertain system parameters. Variable load is seen as a sum of a constant and a variable part. The constant part is regarded as a parameter of the system to be estimated real time. The variable part together with the friction are seen...
This paper addresses the position tracking control problem of electric linear actuator in the presence of nonlinearities due to its transmission process. A torque decoupling approach for electric linear actuator is proposed to achieve respective compensation. To improve the speed of time varying parameters estimating, a load-based adaption law is proposed by designing a new projection mapping which...
