Abstract EN
This work proposes an active disturbance rejection approach for the establishment of a sliding mode control strategy in fault-tolerant operations.
The core of the proposed active disturbance rejection assistance is a Generalized Proportional Integral (GPI) observer which is in charge of the active estimation of lumped nonlinear endogenous and exogenous disturbance inputs related to the creation of local sliding regimes with limited control authority.
Possibilities are explored for the GPI observer assisted sliding mode control in fault-tolerant schemes.
Convincing improvements are presented with respect to classical sliding mode control strategies.
As a collateral advantage, the observer-based control architecture offers the possibility of chattering reduction given that a significant part of the control signal is of the continuous type.
The case study considers a classical DC motor control affected by actuator faults, parametric failures, and perturbations.
Experimental results and comparisons with other established sliding mode controller design methodologies, which validate the proposed approach, are provided.
