Abstract

Abstract

En 中文
The decoupled multimodel framework offers an effective alternative for modeling, control, and diagnosis of nonlinear systems. Its structure relies on interacting with sub-models, with the degree of interaction varying across systems, which directly influences the control design. This paper proposes a novel fault-tolerant control strategy that combines second-order sliding mode control with a multimodel fusion approach to compensate sensor faults. A second-order sliding mode multiobserver is developed to simultaneously estimate the system states and sensor faults. The proposed methodology is validated through a practical implementation on a chemical transesterification reactor, demonstrating its effectiveness and robustness.
