Stabilization of planar switched systems with an output constraint via output feedback

Abstract:
In this paper, smooth output feedback stabilization (OFS) problem of planar output-constrained switched nonlinear systems (SNS) is investigated. Adding a power integrator technique (APIT) is employed to design state feedback controllers in a systematic manner combining with a constructed common logarithm-type barrier Lyapunov function (BLF). Then, by incorporating the variable-gain reduced-order observers designed constructively, switched systems can be stabilized via smooth output feedback and the output constraint is guaranteed simultaneously. Finally, simulations results are shown to exemplify the validity of the method proposed in this paper.

Stability
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...
Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
