Sliding mode observer based sliding mode controller for interacting nonlinear system

Second International Conference on Current Trends In Engineering and Technology - ICCTET 2014, 2014
This paper presents a comparison study of performances and characteristics of two types of state observer based state feedback control schemes, including Sliding Mode Observer (SMO) based Sliding Mode Controller (SMC) scheme and Luenberger observer (LO) based Sliding Mode Control scheme. The effectiveness of the schemes are simulated and implemented on

Adaptive sliding mode current control with sliding mode disturbance observer for PMSM drives

ISA Transactions, 2019
This paper focuses on the current control of a permanent magnet synchronous motor (PMSM) for electric drives with model uncertainties and external disturbances. To improve the performance of the PMSM current loop in terms of the speed of response, tracking accuracy, and robustness, a hybrid control strategy is proposed by combining the adaptive sliding

RLV Sliding Mode Control System Using Sliding Mode Observers and Gain Adaptation

AIAA Guidance, Navigation, and Control Conference and Exhibit, 2003
A novel flight control system for a reusable launch vehicle during Terminal Area Energy Management (TAEM), approach and landing phases of flight is presented. In order to provide accurate tracking and bring the vehicle safely to the landing site, the controller must be robust to external unknown disturbances, unmodeled dynamics and plant uncertainties ...

Sliding mode observers: a survey

International Journal of Systems Science, 2008
Sliding mode observers have unique properties, in that the ability to generate a sliding motion on the error between the measured plant output and the output of the observer ensures that a sliding mode observer produces a set of state estimates that are precisely commensurate with the actual output of the plant. It is also the case that analysis of the

Sliding Mode Control of Robot Manipulators Based on Sliding Mode Perturbation Observation

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2006
This paper presents a sliding mode controller based on a sliding mode perturbation observer (SMPO) for the tracking control of robot manipulators. The SMPO is designed to estimate unmeasurable states and system perturbations that involve system non-linearities, disturbances, and unmodelled dynamics.

Dynamic sliding mode control of pitch blade wind turbine using sliding mode observer

Transactions of the Institute of Measurement and Control, 2022
In a wind turbine (WT), the maximum power can be achieved using a suitable and smooth signal, which should be applied to the pitch angle of the blades (PABLE). On the contrary, the uncertainties of the WT models cause the fatigue due to the mechanical stresses.

Sliding-mode observers for uncertain systems

2009 American Control Conference, 2009
Sliding-mode observer design is considered for linear systems with unknown inputs when the so-called observer matching condition is not satisfied. To circumvent the restriction imposed by the observer matching condition, the method of utilizing auxiliary outputs generated by high-order sliding-mode exact differentiators in the sliding-mode observer ...

Observer based terminal sliding mode control

IFAC Proceedings Volumes, 2013
Abstract A new observer based terminal sliding mode control (TSMC) approach is proposed for a class of second order nonlinear systems which can be used to robotic manipulators, space crafts, satellites and so on. By using equivalent output injection sliding mode observer (SMO) method, the new designed TSMC can achieve finite-time stability ...

FAULT ESTIMATION USING SLIDING MODE OBSERVERS

IFAC Proceedings Volumes, 2007
In this chapter a nonlinear observer using a sliding mode technique is used for estimating the faults, another nonlinear observers are also treated with the purpose of comparing results. An academic example is presented and faults are estimated by each observer. Some numerical results are shown to illustrate this methodology.
